What is a quantum of light? 20, What is a quantum of light?

Einstein postulated that light is made up of energy particles, i.e"Quantum of light", as it was later called"Photons"。This is the first time in the history of human understanding of the natural world that the opposing unity of the wave and particle nature of microscopic objects has been revealed, namely"Wave-particle duality"。This is the most fundamental feature of the entire microscopic world, and it is also the most basic concept of microscopic physical theory.

Later, the research of the photoelectric effect was developed into photocells, sound films, television and other technologies, which have a very close relationship with the modern human civilization life and the utilization of solar energy. Milligan and Compton's precise experimental work finally established the quantum theory of light, for which they were awarded the Nobel Prize in Physics in 1923 and 1927, respectively.

The quantum hypothesis of light was developed by Albert Einstein.

Bold assumptions made. The content is: light has the same particle properties as atoms, and light is a stream of particles moving at the speed of light, and this kind of particle is called light quanta. Same as Planck.

The energy of each light quantum is also e=h, according to the phase lead theory.

, the momentum of each photon is p=e c=h.

Brief introduction. In the years following Planck's quantum hypothesis, which did not arouse interest, Einstein saw its importance. He endorsed the energy child hypothesis and learned important lessons from it:

In existing physical theories, objects are made up of one atom at a time and are discontinuous, while light (electromagnetic waves.

but continuously.

There is a deep contradiction between the discontinuity of atoms and the continuity of light waves. In order to explain the photoelectric effect, Einstein proposed the light quantum hypothesis in 1905 on the basis of Planck's energy quantum hypothesis.

At the beginning of the 20th century, the quantum hypothesis of light was proposed, which solved the photoelectric effect that could not be explained by basic canonical physics.

The word "quantum of light" is explained as "photon".

The explanation of the word "photon" is: that is, the pinyin of "photon" is: guāngliàngzǐ structure is: light (upper and lower structure) quantity (upper and lower structure) and sub (single structure).
