In 1905 a clerk from Switzerland's patent office published three science papers. Two of these research papers solve the problems of photoelectric effect and Ether-light. This notorious cleric quickly became famous. He has changed our concept of the universe. He is our Mr. Universe Albert Einstein (Albart Einstein, 1879-1955).

One of Einstein's three science papers was about the speed of the browser. His second letter was about photoelectric effect.

Keeping in mind Max Planck's quantum hypothesis, Einstein proposed that light is composed of a small quanta or packet (Einstein Newton returns particle theory of light).

Einstein named photon for the light of light. When light hits the electron, the electron comes out of the orbit with energy from the photon.

This energy of photons is synonymous with the frequency of light waves (ie, wave length interrupted). More frequent lighting (such as UV light) is more energy efficient, so they give more power to the electron. Again, low-concomitant light (such as infrared light) is low in photons, so they give less electron power, so the electron can not get out of its orbit.

Photoelectric effects can not be observed so that the infrared light on the metallic material is ignored. Einstein received the Nobel Prize in 1921 for the exploration of photoelectric effect.
