What are some of the debates about the nature of light?

Photons are the medium of light and light waves. Photons fill the cosmic space, have mass and energy, and are a form of existence of matter.

Speculation 1: Photons fill the universe. (China Wang's 2020) speculation two:

Photons are vibrating. (China Wang's 2020) Speculation 3: Photons are fluid.

Wang 2020) The basic properties of photons: photons are particle-like individuals, and photon aggregates are fluctuating. (Wang, China, 2020).

The essence of light is electromagnetic waves. Essentially, light is electromagnetic waves, and the entire electromagnetic spectrum falls under the category of generalized light. The light that our human eyes can see is called visible light, which is a narrow band in the electromagnetic spectrum.

Electromagnetic waves have two characteristics: wavelength and frequency, the stronger the electromagnetic radiation energy, the higher the frequency, and conversely, the lower the energy, the longer the wavelength.

Suppose that the energy of a light wave is not continuous, but fixed at certain values, as if it were composed of many particles (or photons). The strange thing about the diffraction experiment is that the electron waves do not store energy on the entire surface of the detector, which is inconsistent with the generally imagined situation of ocean waves crashing against the shore.

An atom has a certain number of electrons, protons, and neutrons. Protons coexist with neutrons in the nucleus, and electrons "orbit" around the nucleus at a different distance from the nucleus; The distance between the electron and the nucleus is called the electron energy level of the quantum state, and is generally denoted by n. This is a simplified interpretation of Bohr's model.

In the 17th century, there was a debate about whether light was a "function" or an "entity".

Later, it gradually developed into two theories, one is the particle theory represented by Newton, in short, it is believed that light is a stream of material particles emitted from a light source, which propagates at a certain speed in a uniform medium; The other is represented by Huygens's wave theory, which believes that light is a form of vibration that propagates to the surroundings in the form of waves.

The concept of light. Light is a physical term whose essence is a stream of photons in a specific frequency band. The light emitted by the light source is due to the additional amount of energy absorbed by the electrons in the light source.

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. If the transition is followed by just filling the vacancy in the orbital and going from the excited state to the stable state, the electron will not move. Otherwise, the electrons jump back to their previous orbits again and release energy in the form of waves.

The essence of light is to recognize the whole process of light propagation, including the movement of the light source, the propagation process, and the super-distance interaction with other objects. The propagation process of light is due to the movement of the light source object, which drives the electrons to change the motion and rotation, and the connected electrons affect each other and then interact with other objects.

Light is a form of energy that can travel from one object to another without the need for any matter as a medium. This mode of energy transfer is often referred to as radiation, which means that energy travels in all directions in a straight line (within the same medium) from the energy source. As early as the middle of the seventeenth century, Newton and Maxwell elaborated on the "particle theory" and "wave theory" respectively, and it became the theoretical basis for the current theory that light has "wave-particle duality".

Einstein delved deeper into the properties of light, arguing that the waves of light resemble water waves and sound waves. Light waves are a spherical wave. When light diffuses, hail changes, and it forms spherical waves that transmit forward one after the other.

A common phenomenon that Hooke and Huygens used to refute the particle theory was the diffraction of light, which is thought to be characteristic of waves. When the diffraction phenomenon of light was discovered, the wave of light was naturally recognized, and Newton refuted various examples with particle theory against the particle theory proposed by wave theory.

Newton actually gave different explanations for the diffraction of light, he believed that the diffraction of light occurs because the particles in the light are attracted by the gravitational force of the object as they pass through the edge of the object, therefore, it shows that the light is bent at the edge of the object, which can be more successful to prove that light is a particle. The debate about the nature of light has been going on for many years. Finally, Newton's particle theory was recognized for its ability to better explain the various phenomena of light.

The competition for the nature of light, which has so far attracted much attention in the scientific community, ended with the triumph of Newton's particle theory. Since the death of this scientist, this theory has dominated for the past 100 years. It was not until 1801 that wave theory took hold again because the theory of microparticles could not explain Thomas Young's experiments, and in the early 20th century, Einstein joined another scientist as great as Newton.

Inspired by Planck's quantum concept in 1900 and extended it to space propagation, he proposed the quantum theory of light, which proved the existence of light particles in Newton's theory and provided strong support for Newton's theory. Einstein also integrated the particle theory of light and the wave theory, and dialectically proposed that light has wave and particle properties, that is, light is both a wave and a particle. Optics is an ancient science, and many scientists have been trying to explore the nature of light.

Regarding the question of what light is correct in the fluctuating particle school, which is correct, it will be explained here today.

1.Electromagnetic wave.

2.Cosmic ray.

Correct answer: Electromagnetic waves.

The nature of light is still a particularly clear point without explanation, initially through Maxwell's equations, everyone accepted that light is an electromagnetic wave, but after Einstein proposed the photoelectric effect, everyone agreed with the statement of light quanta, and the specific is still being studied and analyzed.

In middle school textbooks, it is proposed that light is a kind of electromagnetic wave, and this explanation is used here, so electromagnetic waves are chosen.

The nature of light is a prerequisite for the existence of life on Earth.

Light is a prerequisite for the existence of life on the earth (of course, there are life forms on the earth that cannot see light, but even if these life forms cannot see light, the energy they ultimately need is indirectly related to light), therefore, the importance of light to human beings is self-evident.

However, the question of what light is has always puzzled people, and many scholars in history have explored the nature of light, the most famous of which should be Newton and Huygens, Newton believed that light is particles, because at that time, in Newton's view, the particle theory can explain various light phenomena very well; Huygens, on the other hand, inherited and refined Hooke's view, insisting that light is a wave. Modern physicists have proposed that light has wave-particle duality.

Light comes from the light source. The reason why the light source emits light is because of the movement of atoms and molecules in the light source, and there are three main ways: thermal motion, transition radiation (including spontaneous radiation and stimulated radiation), and the optical radiation generated by the accelerated motion of charged particles inside the substance.

Light is an electromagnetic wave that can be formed for many reasons, in a broad sense, light can be formed by free electron oscillations (radio waves), stimulated electrons in the outer shells of atoms (infrared, visible, ultraviolet), stimulated electrons in the inner layers of atoms (X-rays), nuclei (Y-rays) which are far away. Sunlight, the most common light in life, is the energy released after the nuclear reaction in the sun, which directly or indirectly releases the surrounding atoms or nuclei from the low energy level to the high energy level, and then from the high energy level back to the low energy level.
