Is a photon a physical particle, please explain in detail!

Microscopic particles have wave-particle duality, both particle and wave, photoelectric effect is particle, interference diffraction is wave, and some experiments can show particle and wave property successively.

Does the landlord want to know the relationship between these "sons"?

Particles are a collective term for these.

1. Atoms, the basic composition of matter, are usually composed of protons, neutrons, electrons, etc. The center of the atom has a positively charged nucleus (made up of protons and neutrons); Around the nucleus there are negatively charged electrons moving around it at high speed.

2. Protons, with a unit positive charge, are one of the components of the nucleus.

3. Neutrons, neutrons are not charged, and like protons, they are also one of the components of the nucleus.

4. Electrons, with unit negative charge. around the nucleus.

5. Photons, it has nothing to do with the previous "sons", it is a component of light, and each beam of light is composed of countless "photons".

6. Quantum: It means "how much" and represents "a considerable amount of something".In fact, it is a kind of unit! For example, a "quantum of light" refers to a photonIt is a unit of measurement for the microcosm.

Microscopic particles, including electrons and light, have wave-particle duality. Wave-particle duality is a property of a particle, which mainly describes the shape that a particle can have in waves. In Newton's time, people began to debate the nature of light.

At that time, Huygens proposed the wave nature of light, and Newton proposed the particle nature of light, but their theories were somewhat different from the observations.

Microscopic particles, including electrons and light, have wave-particle duality. Wave-particle duality is a property, not the essence of light as an electromagnetic wave, in the propagation behavior of the performance of waves, typical is diffraction and interference light in the behavior of interaction with matter is the nature of particles, such as the photoelectric effect and the Compton effect, its action is consistent with the behavior of "particles", photons have momentum and energy, and matter action is also to meet the conservation of energy and momentum.

The motion of microscopic particles is characterized by irregular motion. With the help of microwaves, this irregular motion is turned into regular motion, that is, the molecules vibrate at high speed, the molecules collide with each other, and the displacement between the molecules and the internal air is called friction. This is the most puzzling feature of microscopic particle motion.

When explaining the principle of microwave oven heating, the expert said that the microwave directly acts on the molecules to cause the molecules to vibrate at high speed, and the vibration produces friction and heat, causing the object itself to heat up, and the molecules in the object have been moving irregularly.
