Is light made of photons? What are the answers?

Light is a substance with wave-particle duality.

In this way, light is not only made up of photons, but also has the property of "light waves". <

With the progress of science and technology and the continuous development of physics, there is a fixed standard for the definition of each substance, and "light" is no exception.

There has been a lot of debate in the scientific community about the ontology of the universe, that is, what was before the universe, and the more convincing one is the "universe big **" theory. <

Let's go back 13.8 billion years ago, when all matter in the universe started with the 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 great 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. Singularity, what is Singularity?

The singularity is a thoroughly dense and space-time curvature.

height, and an infinitesimally small "point", but it is not applicable here in common physical principles. <

Through the above facts and examples, we have a preliminary understanding of the two concepts of "light" as a substance and the history of the universe before and after its formation, and the theory with experimental blessings is still credible, but there is still no more accurate concept of "light" as a substance.

It may be wrong, because "light" has what Einstein called wave-particle duality. Light is not only made up of photons, but also "light waves".

No, light has wave-particle duality, which can be regarded as a very high frequency electromagnetic wave, and light can also be regarded as a particle, that is, light quanta, referred to as photons.

Light is formed by various wavelengths, each of which carries different energy, with different frequencies and wavelengths, and these knowledge can be learned in high school, which is very basic.

Probably wrong, because "light" has the characteristics of wave-particle duality, as Einstein said. Light is not only made up of photons, it is also a "light wave". Going deep into the physical image of analogous light waves (quantum mechanics was originally derived from analogous light waves), physical particles are also the peak part of the wave of matter, and also variant particles, jumping.

The wave properties of matter waves are accomplished by the "vertical diffusion virtual field state", which is similar to the perpendicular magnetic field particles in light waves will not be in two places at the same time, but will become a diffusion virtual field state.

At the same time, they spread at all possible locations, passing through all possible paths, and are transformed one by one3354, induced 3354, collapsed3354, autocoherent-decoherent3354, and "path integral" to the shortest path and certain positions. Light is an energy, and the energy in any part of the air in our universe is always interconnected. This is called quantum theory, which means that you are always connected to any object and matter in the universe.

The medium of connection is energy (energy in all its forms), and the speed at which energy travels is infinite (or zero velocity).

Just like time, scientists have been studying the substance "light" for a long time. However, it is difficult to come up with a complete and accurate definition. With the advancement of science and technology and the improvement of physics, there are strict standards for the definition of every substance, and "light" is no exception.

Photon: "How did this substance come about?" Photons did not appear in large quantities as soon as the universe was born. Photons can only exist in light waves, which are essentially electromagnetic waves, which are composed of electric and perpendicular magnetic fields that are independent of each other and have periodicity.

The light wave is then composed of the alternation and mutual conversion of a dynamic electric field and a dynamic magnetic field, and that two-dimensional local electric field (electric vector) is the photon itself (General Physics Volume 3). Photons, then, are mutated particles that occur intermittently. It simultaneously passes (diffuses) through "all possible paths" or "two narrow slits" while converting into an induced perpendicular magnetic field, and is then converted to a new location by the magnetic field induced by SCP-3354.

The correct interpretation is "the jumping motion of the mutated particles" rather than wave-particle duality. According to the theory of relativity, the speed of light is 3*10 to the 8th power, which is 300,000 kilometers per second.

This may be wrong, because "light" has the characteristic of wave-particle duality, as Einstein said, and light is not only made of photons, but also "light waves". With the progress of science and technology and the improvement of physics, there is a strict standard for the definition of each substance, and "light" is no exception. How did the substance "photon" come about, and photons did not appear in large quantities when the universe was born.

It may be wrong, because science is endless, the universe is very mysterious, and no scientist can give an accurate definition.

I think it's possible, because the photon has mass, and it is not static, it exists in the light waves, and it cannot move autonomously, including different frequencies.

For the first time, physicists at EPFL have discovered a way for photons to interact with pairs of atoms. This breakthrough is of great significance for the field of cavity quantum electrodynamics (QED), which is leading the development of quantum technology.

There is no doubt that we are steadily moving towards an era of technology based on quantum physics. But to do this, we must first master the ability to make light interact with matter – or, more strictly, make photons interact with atoms.

This has been achieved to some extent, providing us with a frontier field of cavity quantum electrodynamics (QED), which has been applied to quantum networks and quantum information processing. Still, there's still a long way to go. Currently, the interaction of light with matter is limited to a single atom, which limits our ability to study them in complex systems involving quantum technology.

In an article published in the journal Nature, researchers in Jean-Philippe Brantut's group at EPFL's School of Basic Sciences have discovered a way to "mix" photons with atomic pairs at ultra-low temperatures.

The researchers used the so-called noisy Fermi gas, a state of matter made up of atoms that resembles electrons in a material. "In the absence of photons, gases can be prepared in a state where the interaction between atoms is very strong, forming loosely bound pairs," Brandt explains.

When light is sent into a gas, some of these pairs can be absorbed by photons into chemically bound molecules. ”

A key concept of this new effect is that it occurs "coherently", meaning that photons can be absorbed, turning a pair of atoms into a molecule, which is then emitted back and then reabsorbed multiple times. "This means the formation of a new type of 'particle' – technically an excitation – for the photonic system, which we call a 'polaron,'" Brantut said. "This is made possible in our system, where photons are confined to an 'optical cavity' – a closed box that forces them to interact strongly with atoms.

Mixed-polarization pairs have some properties of photons, which means they can be measured optically. They also have some properties of Fermi gas, such as the number of atomic pairs of Fermi gas before photons enter.

Some of the very complex properties of the gas translate into optical properties that can be measured directly without even disturbing the system," Brantut said. "Future applications will be in quantum chemistry, as we have shown that some chemical reactions can be produced coherently with a single photon. ”
