Is light a particle or a wave, and a particle or a wave?

Light has wave-particle duality early in the morning.

Among them, the light only wave was proposed by Huygens.

Light particles were proposed by Newton.

Quantum theory can be used to perfectly explain the wave-particle duality of light.

I only know that no matter how deep these skins are, I don't know how to pull, forgive me for being a shallow learner.

Einstein's special theory of relativity says that light is made up of photons, but light travels in the form of waves, so light is both a particle and a wave.

A photon is a type of particle that is smaller than an electron.

The double-slit experiment shows that light has an interference effect, which is the criterion for judging waves.

Einstein's photoelectric effect is the embodiment of particle.

Light has wave-particle duality, which is only a particle and a wave.

Light is both particulate and wavering.

In fact, according to de Broglie's theory, any object is fluctuating. This wave is called a de Broglie wave, so do you say you are a wave or an object?

The photon is spoken of in terms of his energy separation. There are no photons one by one.

Other things also have wave-particle duality. electrons, electromagnetic waves, and much more.

It doesn't matter if you don't understand it, there are many things in physics that are contrary to the basic common sense of people. Human common sense is often only at the level of the basic manifestation of matter, and people who have not studied physics will definitely think that force is the cause of the motion of objects. However, this is not the case, because this small "inertia" has opened the prelude to the blossoming of a hundred flowers from the time of Galileo to modern physics.

People can only feel three-dimensional space and one-dimensional time, these four-dimensional space-time, and this world is far from what we see.

Photons are one of the particles and have nothing to do with light!!

Albert Einstein said, "Light is a wave through a continuum. ”

Light has wave-particle duality, double slit can explain wave, and photoelectric effect can explain particle.

Light has wave-particle duality.

The nature of the existing wave.

And there are the properties of particles.

Light is both a particle and a wave, but generally acts as a wave.

Double-slit interference experiment - this is known as the most terrifying experiment in quantum mechanics, where is the horror?

The current knowledge of physics is only known as wave-particle duality!!

Light has diffraction and refraction, which is indeed a property of waves; But the participation of light in photoelectric action conclusively proves that light is a particle, it is like both waves and particles, and we call it "doing".Wave-particle duality

In fact, not only light, but any subatomic particle, whether protons, neutrons, electrons, etc., is both like a wave and a particle in motion, and these particles can be refracted and diffracted in precision-engineered experiments, rather than moving in a straight line.

Light has energy, and of course there is mass, which is known to anyone who studies physics. The monitor in front of you shines on you, and because light has mass, you are oppressed by the pressure generated by this light (light pressure), but it is so tiny that you are unconscious.

Background: The history of the study of light, like mechanics, has been noted since the time of the ancient Greeks, and the law of reflection of light was known as early as Euclid's time, but before the separation of natural science from religion.

Human beings' understanding of the nature of light has hardly progressed, and it has only stayed at the level of understanding of the propagation and use of light. ( On the other hand, history tells us that ancient China.

As early as the early Warring States period, Mozi, the founder of Moxue.

He 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 wave theory and the particle theory.

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 the famous German physicist Planck.

and several other scientists established quantum physics.

It is said that the human understanding of the properties of matter has been completely expanded.

To sum up, the essence of light should be considered as photons, which have 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, according to Einstein's mass-energy equation.

Its mass can be calculated.

Wave.

Light is a physical term whose essence is a stream of photons in a specific frequency band. A light source emits light because the electrons in the light source gain extra energy. If the energy is not enough to make it jump to a more outer orbit, the electrons undergo an accelerated motion and release the energy in the form of a wave.

Characteristics of light. 1. In geometrical optics, light travels in a straight line. This is illustrated by the straight pillars of light and the sun's rays.

2. In wave optics, light travels in the form of waves. Light is like water waves on the surface of the water, and different wavelengths of light appear different colors.

3. The speed of light is extremely fast. 299792458 3 10 ms in a vacuum, slower in air. In media with a larger refractive index, such as water or glass, the propagation speed is even slower.

Light is neither a wave nor a particle.

Light is a microscopic form of material existence. There are many microscopic forms of matter, and light is only one of them, which has the properties of both waves and particles, or rather, it behaves like waves and particles, and has wave-particle duality. Light has diffraction and refraction, which is indeed a property of waves; However, the participation of light in photoelectric action conclusively proves that light is a particle, which is both like a wave and a particle, which we call "wave-particle duality".

Light has diffraction and refraction, and it is indeed the annihilation of waves; However, the participation of light in photoelectric action conclusively proves that light is a particle, which is both like a wave and a particle, which we call "wave-particle duality". In fact, not only light, but also any subatomic particle, whether protons, neutrons, electrons, etc., are both like waves and particles in motion, and these particles can be refracted and diffracted in precision-engineered experiments, rather than moving in a straight line.

Causes of light formation

The first category is the light produced by the thermal effect. Sunlight is a good example because the surroundings are cooler than the sun, and in order to achieve thermal equilibrium, the sun releases energy in the form of electromagnetic waves until the surrounding temperature is the same as it.

The second type is atomic transition luminescence. The fluorescent substance applied to the inner wall of the fluorescent lamp is excited by the energy of electromagnetic waves to produce light. In addition, the principle of neon is the same. Atomic luminescence has its own characteristic spectral lines. Scientists often use this principle to identify elemental species.

The third type is the light produced when the charged particles inside the substance are moving at an accelerated pace. For example, synchrotrons emit synchrotron light that carries a lot of energy.
