    Light is indeed a particle, but it is also a special electromagnetic wave with "wave-particle duality"; There are many versions of how photons are created, but none of them have the empirical evidence to convince everyone. Suppose, one day, we really prove the specificity of the photon;

    Then, you will definitely be able to win a Nobel Prize. We all know that in the universe, the most amazing power is "light". It is the existence of light that allows human beings to survive and reproduce until recently, and it is the light that gives plants the photosynthesis that allows them to flourish and grow;

    It is the speed of light that determines the basic order of the universe, and every corner of every aspect, that makes a big difference in the way human beings exist. However, the "sacredness" of light has sparked a vigorous debate in the scientific community, and even today, there is still no concrete result of the debate about the various properties carried by light.

    What is light? Some people say that light is a particle, also called a "photon"; It has been said that light is an electromagnetic wave, and Maxwell's equation has been measured in the last century. Which of these two statements is true? The answer is, all correct.

    In the nineteenth century, we have discovered that light is not only a specific particle, but also has the fundamental property of electromagnetic waves, and photons will interfere with each other, so we explain it as the "wave-particle duality" of light in junior high school physics.

    As for what photons are, this question is still plaguing us on the road of scientific development, and the academic community has never stopped discussing. Before the double-slit experiment, many people thought that light was made of "ether";

    Although the "ether theory" is no longer the dominant view, there is still no tangible evidence to explain what the light really is. At the same time, in superstring theory, the source of photons is again "strings"; It is the constant vibration of the strings;

    so that the photons can gradually accelerate to the "speed of light".

    Yes. Because light is also a particle, it is called a light particle. It is generated by the nuclear reaction of the sun and carries the energy of the nuclear reaction, so it can reach the speed of light.

    Light is indeed a particle, but it is also a special electromagnetic wave with "wave-particle duality". At the end of the day, speed itself isn't really important. After all, it has units :

    Meter seconds. In physics, any number with units can change its value, because we first have to define its units. For example, in order to express the speed of light in the form of "meter seconds", it is first necessary to decide what exactly "one meter" and "one second" mean.

    Therefore, the definition of the speed of light is closely linked to the definition of length and time.

    In physics, we focus more on those constants that have no units or dimensions, i.e., numbers that exist only in numerical form in physical theory. These numbers seem to be much more basic because they don't need to rely on any definition. In other words, if we get acquainted with an extraterrestrial civilization in the future, we may not be able to understand the speed of light they measured, but we can agree on constants that have no dimension, because they are just numbers.

    It is also a special electromagnetic wave, the source of the photon is the string, and it is the vibration of the string that allows the photon to accelerate to the speed of light.

    Light is a class of particles, photons generally release energy due to electron transitions outside the nucleus, and energy is released in the form of photons.

    The power of light comes from the moment when the light is generated, and it can continue to move in a straight line without encountering resistance, and the speed will decrease until it stops when encountering resistance.

    The essence of light is a reaction at the atomic nucleus level, and the propagation power of light is also the power generated by the action of protons and electrons in the nucleus.

    Light itself is an electromagnetic wave, and although there is no air in a vacuum environment, there are elements, atoms, electrons, and protons, which become the propagation medium of light.

    This is the same magnitude of effect, just like a nuclear bomb, although the appearance of one is a nuclear bomb, the others are houses, houses, trees, but the smallest unit is the atom, the nucleus, which directly resonates from the frequency of the atomic level, and directly destroys from the core, and it does not matter whether you are a house, a tree or a person, directly destroy the nucleus that disturbs you, and it will be directly destroyed.

    Light is the effect of the order of electrons, and the power of light propagation is also the power generated by the action of positive and negative charges. The disappearance of light is actually a conversion of energy, from visible light to invisible light, or heat energy, or other forms of energy.

    Where does it come from? It is supplied by the movement of charged particles when light is generated. Light is an electromagnetic force, in the process of propagation, no medium is needed, no energy loss, no force is consumed, and the field speed is always maintained and cannot be stopped.

    Light is essentially an electromagnetic wave, that is, an alternating electric and magnetic field. It is the medium of energy and material transfer, when the electrons around the nucleus absorb photons, they will jump to a higher energy level orbit, and the electron transition will also produce a changing electric field, which will naturally affect the light that is essentially an electromagnetic wave, which is the light decay and the slowdown of the speed of light seen by vision.

    Light has wave-particle duality, the amplitude decreases and the energy consumption is reduced until it is not vibrating, the light has no mass, it will not be affected by gravity, and there is no resistance, and the speed is constant, so it cannot stop, but it will be absorbed when it is blocked by matter. The power of light is the essential characteristic of light, and light is a kind of energy.

    Photons don't need power at all, they always maintain the speed of light and don't need power at all.

  8. Anonymous users2024-01-30

    The reason why it generates power is that due to the existence of the Siggs field, all kinds of particles will be slowed down to gain mass, and the price is that the matter composed of particles can never reach the speed of light, so the propagation speed of photons can always maintain the speed of light, so the power is generated.

    Once a photon is generated, its speed is a constant speed of light, and there is no acceleration process to "reach the speed of light", and because there is no need for power to drive during the propagation of photons, there is no "where does the power come from".

    Photons do not need to be driven to speed up in a vacuum pump to reach the speed of light, and since stationary photons have no mass, the speed is the speed of light, which is their original speed.

    Since the advent of health on the earth, light is an indispensable being, light is energy, and photons are a part of energy. Green plants use plant photosynthesis to convert solar energy and store it in organic compounds. This energy is then transmitted upwards according to the biological chain, and all the lives of the earth are enshrined.

    Sunlight is emitted by the sun, and as a planet, nuclear fusion reactions are constantly undergoing inside it, and the damaged mass is converted into energy according to Einstein's mass-energy equation.

    Light has been evolving with the development trend of human history, but people's understanding of it is very short-lived, Galileo was the first person to gradually systematically and accurately measure the speed of light, but the speed of light is very large, and ordinary methods cannot be accurately measured.

    Photons have no lifespan, and it can be said that they are eternal beings, only to be adsorbed and released, otherwise they will continue to fly in deep space until they remain unchanged. According to the time dilation utility of Einstein's special theory of relativity, photons have no rest quality, and their speed is the speed of light, which means that time is not dead and does not disappear, which also represents an eternal and unchanging service life.

    Through the diligence of generations of scientists, the value of the speed of light has become more and more accurate. In other words, the creation of light is a gradual counting, and the speed is of course the speed of light, and there is no need to speed up the whole process at all, because light has no static quality, it cannot be described by Newton's second fundamental law.

    Biologists have contradictions about the nature of light, which not only has the characteristics of particles but also the appearance of light, and has been arguing for nearly a hundred years from beginning to end, and the final result is that light has wave-particle duality, which is both radio waves and photons, and its energy is all in the form of quantum technology, showing a share of the situation.

    Therefore, the speed of more than 300,000 kilometers per second in the photon vacuum pump does not need the driving force to accelerate, and at the same time, it does not need the driving force to maintain, because there is no static quality The speed of more than 300,000 kilometers per second is their own characteristic.

    All in all, through the scientific research and testing of many scientists, the photon does not need a driving force to achieve the speed of light, because the photon is in a vacuum pump, it does not need to accelerate to achieve the speed of light.

    Photons will fly at the speed of light when they are born, and will not be affected by the outside world and will not lose energy.

    Light is just an elementary particle, which will fly at the speed of light from the beginning of its birth and will never stop, unless it is affected by external forces, because of the special structure, so the speed is so fast.

    It uses its own energy. Because its own energy is very strong, it can have a certain driving force, which makes the speed very fast.

    It should be using the power of air propagation, and then reaching the speed of light in an instant, because photons need to reach the speed of light, which is actually very difficult.

    Whether there is a substance that moves faster than light, this depends on the definition of speed, and there are two things whose speed of change is indeed faster than lightBut it can't be called velocity, one is the expansion rate of the visible universe we live in now, and the other is quantum entanglement between quanta. <>

    The expansion rate of the visible universe is now known to us, the diameter of the visible universe is 93 billion light years, that is, the speed of light has traveled a year, the diameter of the entire universe is 93 billion light years, which is what we can observe now, but our current observable universe is constantly expanding, it is getting bigger and bigger, which is a bit like the shock wave generated at the time of ** is constantly affecting outward, but this year has been quite long, Because the life span of the universe as we know it now has reached 100 million yearsIt has been spreading for so long and it has not stopped, and the speed of this diffusion is faster than the speed of light. <>

    When a pair of quanta is entangled, the speed of this inductive force, this can not be strictly called speed, a pair of quanta no matter how far apart it is, one of the quanta has changed, the other quantum will occur synchronously, the change of attention is completely synchronized, there is no time delay and no distance limit, even if one of the quanta is on the earth, the other is in space, the two of them will change synchronously, it is so magical and so terrifying, but these two are a strange attraction,He could not understand such a process as a velocity, because it did not have a change in the trajectory of matter in space. <>

    The relativity theory of the market has said that the speed of light is constant and unsurpassable, that is, if you want to find a substance that is faster than the speed of light, and the definition of speed is in line with it, then the first thing you have to do is to break the relativity theory of industry assets, which first proves that its relativity theory is wrong, but for now,No scientist has yet been able to propose something that everyone agrees to be able to exceed the speed of light and prove Einstein's theory of relativity wrong.

    Light is composed of photons as elementary particles, which have particle and wave properties, which is called wave-particle duality. Light is an electromagnetic wave (visible spectrum) that can be seen by the human eyeIn the scientific definition, light sometimes refers to the entire spectrum of electromagnetic waves.

    Light is made up of a type of elementary particle called a photon. The study history of light is the same as that of mechanics, which has attracted attention in the ancient Greek era, and the law of reflection of light has been known as early as Euclid's time, but before the separation of natural science and religion, human understanding of the nature of light has hardly progressed, and it only stays at the level of understanding of the propagation and use of light. (In addition, history tells us that as early as the early Warring States period in ancient China, Mozi, the founder of Moxue, discovered the law of reflection of light and established China's optical system.)

    In the seventeenth century, there were already two voices on this issue: the Dutch physicist Huygens put forward the wave theory of light in his book "On Light" published in 1690, deduced the law of reflection and refraction of light, and satisfactorily explained the reason why the speed of light decreases in the light-dense medium, and also explained the birefringence phenomenon caused by sunlight when light enters the ice-island stone; In his book "Optics" published in 1704, he proposed that luminous objects emit particles moving in a straight line, and the stream of particles hits the retina to cause vision, which can also explain the refraction and reflection of light, and even after modification, it can also explain the phenomenon of "diffraction" discovered by Grimaldi. In the nineteenth century, the British physicist Maxwell introduced the concept of displacement current, established the basic equation of electromagnetism, and founded the electromagnetic theory of light, by proving that the speed of electric microwave propagation in a vacuum is equal to the speed of light propagation in a vacuum, so as to deduce that light and electromagnetic waves are essentially the same, that is, light is an electromagnetic wave of a certain wavelength.

    In the twentieth century, quantum theory and relativity theory were established one after another, and physics entered modern physics from classical physics. In 1905, the American physicist Albert Einstein proposed the famous photoelectric effect, believing that when ultraviolet rays irradiate the surface of an object, they will transfer energy to the surface electrons, so that they can get rid of the constraints of the atomic nucleus and release them from the surface, so Einstein interpreted light as a collection of energy - photons. In 1925, the French physicist de Broglie put forward the theory that all matter has wave-particle duality, that is, all objects are both waves and particles, and then several scientists such as the famous German physicist Planck established the theory of quantum physics, which completely expanded the understanding of human beings on the properties of matter.

    To sum up, the essence of light should be considered as "photon", which has wave-particle duality. However, the meaning of the wave here is not a mechanical wave like sound waves and water waves, but a wave in a statistical sense, that is, the nature of the wave reflected in the behavior of a large number of photons. At the same time, light has a dynamic mass, and its mass can be calculated according to Einstein's mass-energy equation.
