Webb百科解释. In the photoelectric effect, electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as ultraviolet radiation. Electrons emitted in this manner may be referred to as photoelectrons.

Webb3 apr. 2024 · One of the important causes of the Photoelectric Effect is the absorption of the light energy by the electrons at the metal surface. The electrons use this light energy to overpower the forces binding them to the nuclei of the metal. The photoelectric effect was discovered by the German physicist Heinrich Rudolf Hertz in 1887. WebbFactors Affecting Photoelectric Effect Photoelectric current is produced as a result of photoelectric effect; therefore, understanding the factors which influence the photoelectric effect is very important. The previous studies on photoelectric effect have presented the following factors which may have a direct impact on photoelectric effect. 1.
