What is the principle of making the speed of 30 kilometers per second and the same speed of electrom

Because light itself is also an electromagnetic wave. Light has immeasurable kinetic energy because it does not have mass in the process of traveling. As a result, it can orbit at a speed of 300,000 kilometers per second in any space in the universe.

As we all know, in the 21st century, mankind has made countless achievements and progress in many fields of natural science.

However, to this day, with the vastness and vastness of the universe, there are still many unsolved mysteries of mankind that have not yet been verified. For example, one of the most mysterious forces we have discovered in physics to date: the speed of light.

The speed of light is almost the benchmark for measuring the three-dimensional world, determining the rules of the universe; Moreover, according to the architecture of Einstein's general and special theories of relativity, the speed of light is also the frame of reference for "space-time". So, many friends must be very curious about why in the universe, the speed of light, as the upper limit of the speed of any object, is limited to 300,000 kilometers per second;

Moreover, the speeds of light and electromagnetic waves are almost exactly equal. What's the secret behind this? Actually, the answer is very simple.

Friends who have a certain understanding of physics should know that in the nineteenth century, scholars discovered that light has wave-particle duality through the "double-slit interference experiment of light".

Light is not only a particle but also an electromagnetic wave during propagation, therefore, it does not require any medium for its propagation. Light and electromagnetic waves have the same velocity, of course, as it should be. After all, they're of the same nature.

But what about the energy that moves at the speed of light? This goes back to the various electrons inside the particles. Under the adsorption of electrons in the center of the particles, excess energy will be dissipated, forming the kinetic energy of light flight;

Since light itself does not possess any mass, even if it has any kinetic energy attached to it, it will immediately magnify to infinity. Therefore, it will be able to reach speeds of 300,000 kilometers per second. This is what we commonly refer to as the "speed of light".

This is because electromagnetic waves come from a type of light, so they will have the same velocity, which can be achieved using a particle accelerator.

Because light is a form of electromagnetic waves, and the speed of electromagnetic waves in a vacuum is 30 kilometers per second, their speeds will be the same.

The speed of light, according to the architecture of Einstein's general and special theories of relativity, is also the reference frame of "space-time". So, many friends must be very curious about why in the universe, the speed of light, as the upper limit of the speed of any object, is limited to 300,000 kilometers per second;

Answer: The speed of electromagnetic waves.

The speed of copy is the same.

An alternating electromagnetic field, known as electromagnetic waves, that propagates in space. The speed of its propagation in a vacuum is the velocity of propagation in a vacuum c=.

The electromagnetic spectrum, radio waves, infrared, visible light, ultraviolet, X-rays, rays, and R-rays are all electromagnetic waves.

In the same way, light waves are a type of electromagnetic waves.

Light has wave-particle duality, and bending skin is also a type of electromagnetic wave.

The velocity of electromagnetic waves in a vacuum is equal to the speed of light in a vacuum.

The velocity is related to the refractive index when propagating in a medium, the greater the refractive index, the smaller the velocity, and in the same medium, the longer the wavelength, the smaller its refractive index and the greater the propagation velocity.

Light slows down in the medium, and the higher the refractive index, the slower.

Scientists in the United States have succeeded in increasing the refractive index of the pure answer of the medium. The medium they use is composed of a cloud of ultra-low temperature atoms after laser application. The researchers first cooled a cloud of large numbers of sodium atoms to near absolute zero to form the so-called "Bose-Einstein condensation", in which the speed of the atoms is almost zero, and the sodium atoms are forced to overlap each other and come to rest, forming a kind of "condensate".

Subsequently, the scientists used a laser beam to process the "condensate", drastically changing its refractive index. When a yellow laser beam was passed through the treated "condensate", a significant decrease in the laser speed was successfully observed. The speed of light was reduced to a minimum of 17 meters per second.

But why?

Light slows down in a medium because of the absorption and re-emission of photons by the atoms of the medium, and the true speed of light is never the same.

Just like a mirror reflects light, it's actually a mirror that absorbs photons and emits them! Instead of bombing the light out as we imagined.

On this subject, the results of scientists have proven that because light has a wave nature, it is also an electromagnetic wave, which is an electromagnetic wave with an extremely high frequencySo he is much higher than the electromagnetic waves used for broadcasting. Light of such colors as red, orange, yellow, green, blue, indigo, violet, and other colors, their frequencies are between 10000000 megahertz and 1 billion megahertz, while the frequencies of radio waves are below a few megahertz, and as for the invisible infrared, ultraviolet lamps are also electromagnetic waves.

But the frequency of infrared light is lower than that of visible light, and the frequency of ultraviolet and C-rays is higher than that of visible light. Because light is also an electromagnetic wave, but its frequency is very different from the electromagnetic wave used for broadcasting, and the difference in frequency does not affect the speed of their propagation in the atmosphere, therefore, their transmission speed is all 300,000 kilometers s, and the speed itself is actually a concept of physics, and it is also a terrible catalyst that can speed up the heartbeat and generate excitement.

The pursuit of speed itself is the dream of our human beings, in the long history of human cognition, people have always believed that the speed of light is invisible, with the development of science and technology, the ability of human beings to understand the world has been improved. In the process of exploring the mysteries of the universe, people began to speculate whether there is a faster speed than the speed of light in the universe, in fact, many people do not know, fast and slow are relative, but we cannot draw a conclusion from this.

For example, the speed of all objects is different from the speed at which the reference system moves at different speeds, his answer is no, because the speed of light itself is an exception, experiments and calculations have proved that the speed of light in a vacuum or air has nothing to do with the motion of the reference system, and is always a constant c, the measurement of the speed of light on a stationary or superspeed rocket is also constant, and the state of motion, including velocity, the magnitude of the direction of the light source is independent of the speed of light, that is, the principle of the speed of light is narrowly relative.

Regarding the question of what is the principle of making the speed of optical and electromagnetic waves 30 kilometers per second, we will explain it here today.

Light is essentially electromagnetic waves, so it naturally travels at a speed of 300,000 kilometers per second.

In science, the speed of light is generally not rounded, because this can better reflect the rigor and logic of science, and this method can only be applied to occasions where the logic is not very strong. <>

The speed of light is so incredible that it can easily destroy the universe, but why is it harmless to humanity? This phenomenon is due to the fact that the momentum of light is very low. The meaning of the term momentum refers to the product of the velocity of a substance and the energy produced by its mass, for example

The weight of the sand is considered to be kilograms, and its speed is 1 s, so the momentum of the sand is, so it will not cause harm to the human body, because light is the existence of a special substance, and its mass is zero, according to the calculation formula of momentum, the momentum of light is zero, and it will not cause any harm to the human body. <

From the speed of light can be associated with photons, how did photons come about, photons did not exist at the beginning of the universe, about the question of what the universe was before the more reliable is the theory of "the universe is big". 13.8 billion years ago, when all matter in the universe started with a singularity. After the singularity**, the present universe and everything were formed.

In the early stages of the history of the formation of the universe, the entire universe was in a state of high temperature. It develops in a rapidly expanding state, leaving behind a substance called "glow". <

The theory of the universe is accurate that this glow should develop in the form of microwaves, and it is in a visible state. As expected, scientists used the precision equipment of orbital probes to accurately measure the possibility of the existence of cosmic microwave backs, which provides a factual basis for the correctness of the big ** theory.

Through the above facts and examples, we have a preliminary understanding of the two concepts of "singularity" and the history before and after the formation of the universe, and the theory with the blessing of experiments is still credible.

In a sense, light is also an electromagnetic wave, but it is different from the electromagnetic wave frequency that we usually see. So it's normal for light and electromagnetic waves to travel at the same speed, because it's the same thing at its root.

1.To correct it, the speed of light and electromagnetic waves is 300,000 kilometers per second.

2.Light is also a type of electromagnetic wave, and the wavelength range of electromagnetic waves i is very wide, and the wavelength range of light is included in it, and light can be considered as a type of electromagnetic wave.

3.Light has characteristics that are different from general electromagnetic waves, so light has wave-particle duality, that is, light has the characteristics of waves, such as interference, derivation and other phenomena;

Because according to scientific research, light is also a wave, Einstein proposed the wave-particle duality of light, which shows that the average light behaves as a fluctuation for time; For the instantaneous value of time, light behaves as a particle.

On February 22, 1857, the famous German physicist Hertz was born in Hamburg. Hertz measured that the speed of electromagnetic waves is equal to the speed of light. Radio stations use electromagnetic waves to transmit sound, but the frequencies of electromagnetic waves used by each radio station to broadcast are different.

Close-range broadcasting, generally using frequencies of several hundred to several thousand kilohertz, is called medium wave; Long-distance broadcasting uses electromagnetic waves with frequencies of a few megahertz (1 megahertz is 1 million electrical oscillations per second). Although the frequencies of the various bands are different, they all travel at speeds of 300,000 kilometers per second.

The results of scientific research have proved that light is fluctuating, and light is also a kind of electromagnetic wave, and it is an electromagnetic wave with a very high frequency (much higher than the electromagnetic wave used for broadcasting), such as the red, orange, yellow, green, blue, indigo, violet and other colors of light that we can see in ordinary times, their frequencies are basically between 100 million megahertz and 1 billion megahertz, while the frequency of radio waves is below a few megahertz. As for those invisible rays - infrared, ultraviolet rays, etc. are actually electromagnetic waves, but because the frequency of infrared rays is lower than that of visible light; The frequency of ultraviolet and X-ray rays is higher than that of visible light. Because light is actually an electromagnetic wave, but the frequency is very different from the electromagnetic wave used for broadcasting, and the difference in frequency does not affect their propagation speed in the atmosphere, so their propagation speed is 300,000 kilometers per second.

If these electromagnetic waves are arranged in the order of wavelength or frequency, they become the electromagnetic spectrum. If the frequencies of each band are arranged from low to high, their order is power frequency electromagnetic waves, radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and R-rays. The wavelength of radio is the longest, and the wavelength of cosmic rays is the shortest.

Light and electromagnetic waves are both the smallest particles that are excited, so they are both excited quanta. The difference between the two is simply the difference in their energy. Moreover, the greater the energy, the more particulate it is; The lower the energy, the more volatile.

Their velocities are not the same, light is 3 times 10 to the 8th power of meters per second, and electromagnetic waves are about 3 times 10 to the 5th power kilometers per second.

Scientific research data prove that light has fluctuations and is one of the most frequent electromagnetic waves, because for this reason, light is only different in frequency from electromagnetic waves used for broadcasting, and does not affect their propagation speed in the atmosphere.

The velocity of light and electromagnetic waves is the same in a vacuum, and the velocity cannot be the same where it is not a vacuum.

According to scientists, light is composed of a type of elementary particle called a photon, and it has particle and wave properties. Electromagnetic waves are not only the same as light, but also have the same reflective, refractive and polarization properties, proving that light is essentially electromagnetic waves.

The distance is not related to the velocity, nor is it related to the problems you mentioned.

It is related to the intensity decay speed of the propagation process of electromagnetic waves, and the so-called "not far" is not that the electromagnetic waves have not been transmitted far away, but that the signal has been too weak to be received in the noise "far away". For example, when an electromagnetic wave passes through a medium, the electric field will cause the polar molecular atoms in the medium to change their displacement, and the higher the frequency, the more times the molecular atoms overturn over friction per unit time, and the greater the energy loss; The magnetic field will also interact with the medium, and it is well known that the faster the magnetic field changes, the more obvious the magnetic induction effect; There are also obstacles in the transmission space also have a blocking effect, the larger the size, the more significant the blocking effect, the size is not measured by geometric dimensions, but measured according to the wavelength; These are the reasons why the higher the frequency, the greater the loss.

However, there are exceptions, there are no such problems in a vacuum, and there is no such thing as a short distance for high-frequency electromagnetic waves.
