Who came up with the wave particle duality of light

The wave-particle duality of light was proposed by Albert Einstein de Broglie.

Nature is also the same as exploring the nature of matter. Historically, physics has revolved around whether matter is a wave or a particle.

The task of optics is to study the nature of light, the laws of radiation, propagation and reception of light; The interaction between light and other substances (such as the absorption and scattering of light by substances, the mechanical action of light and the thermal, electrical, chemical, and physiological effects of light, etc.) and the application of optics in science and technology.

Is light a particle or a wave? What is the wave-particle duality that has caused headaches for countless physicists?

Refer to the photoelectric effect, the Compton effect, and double-slit interference experiments.

First, under the high-speed motion of the object, the moving mass will become larger, which is the reasoning of the special theory of relativity. But one of the derived premises of special relativity is the recognition that photons move at the speed of light in any frame of reference. So you can't use the conclusion to doubt the premise of the conclusion.

That is, the photon velocity is the speed of light, and it does not slowly approach the speed of light from a low velocity, so there is no inference that the photon acceleration process makes the mass infinite.

Second, light is a frequency band in electromagnetic waves, and of course there are sinusoidal changes in electric and magnetic fields. Light is electromagnetic waves, but before people realized that light is electromagnetic waves, this visible electromagnetic wave was named "light". In other words, visible electromagnetic waves are light.

Electromagnetic waves in other frequency bands can also be "seen" with instruments. Night vision devices are seen in the infrared frequency band.

Analysis: The interference, diffraction, and polarization phenomena of light all prove that light has wave, and the photoelectric effect and Compton effect prove that light has particle. It is not possible to explain all light phenomena with one of these properties, so light has wave-particle duality.

Wave and particle properties are not evenly expressed, a large number of photons exhibit volatility, and individual photons exhibit particle. Light exhibits wave when propagating and particle when interacting with other substances, with significant fluctuation when the wavelength is long and particle significant when the wavelength is shorter, and light wave is a probabilistic wave.

d correct. Item A should be that light has the properties of both a wave and a particle; B photons and electrons are two kinds of particles, the electron is a fermion, and the photon slag is a boson; Clause c Because according to quantum theory, all matter has waves, but the De Broy waves of macroscopic objects are very small, and the fluctuations of microscopic particles are more obvious. The volatility of light is the collective manifestation of the volatility of photons.

But the volatility of light is classical volatility and is the result of the variation of the electric field with space and time. The volatility of the photon is a kind of rolling probability wave, which is a manifestation of the uncertain position of the photon. The bunching and reconcentrating effects of photons cannot be understood as a result of photon-to-photon interactions.

So item d is correct.

After many iterations from experiment to theory and theory to experiment, its final establishment went through three processes: first, the establishment of the concept of light quantum, second, the determination of energy particles (quantum states in atoms), and third, the determination of the wave-particle duality of material particles.

Experiments (some were only thought experiments at the time), one is to confirm the light quantum of black-body radiation, photoelectric effect, Compton effect and other residual experiments; The second round of destruction is a spectroscopic experiment to confirm the quantum state in the atom, the Frank-Hertz experiment, etc.; The third is to confirm the wavy Davidson-Gram experiment and the electron bi-collision interference experiment.

Physics textbooks tell us that photons have both wave and particle properties, and that they can be observed through the famous double-slit interference experiment.

Later, we proved that the experiment was wrong, because the equipment we were using to observe would generate electromagnetic interference, which would affect the results of the experiment and lead to wrong conclusions.

As for how it turned out to be wrong, the conclusion is that the observation equipment was turned off and everything was back to normal, but how did you get the conclusion? Individuals are not clear.

However, this led to another experiment, which is called a blind man touching an elephant.

In the experiment of the blind man touching the elephant, the blind people came to different conclusions, some people said that the elephant was like a tree, some people said that the elephant was like a fan, some people said that the elephant was like a rope, and the conclusions were different. This is the one-sidedness of our observation.

The reason why I say that the blind man touches the elephant is to point out that the experiments we do are only a one-sided observation of the characteristics of things, like a leopard in a tube, only a glimpse.

There is another reason, whether the characteristics of the things that we observe, whether they are what we observe, or whether the things that we observe because of our observations, well, this is a bit idealistic.

To put it simply, when we observe a person, we come up with the result of our observation, and this result is what we observe, or do we observe this person, and this person knows that we are observing.

Come to think of it, this conclusion may be a bit unscientific, but when science can't explain all the problems, we can only observe and verify it little by little.

In our finite lives, I.

The knowledge we have gained is all taught by our predecessors and our own experience.

Each of us does not see the world exactly the same, which means that there are a thousand Hamlets in the eyes of a thousand people.

Although we are all seeking common ground while reserving differences, are the results we observed, or are they formed because of our observations?

Maybe that's one of the biggest unknowns, right?
