Light shines on some of the material,causing changes in electrical properties of matter,light energy is converted into electrical energy.Photoinduced change of such a phenomenon is collectively known as the photoelectric effect that people
Photoelectric effect is an important and mysterious physics phenomena,in the light irradiation,some of the material inside the electron-photon excitation will be formed out of the current,which photo-electric.Optical phenomena by the German physicist Hertz in 1887 found that while the correct interpretation of Einstein proposed.Scientists in-depth study of the photoelectric effect on the development of quantum theory has played a fundamental role.
That Einstein would have to Tipu Planck,Einstein,Planck is the founder of the photoelectric effect,Planck can not say there is no photoelectric effect,Einstein was inspired by his 已经尽力速度回.望采纳0v0
