Q.2 Explain the statement that one’s eyes could not detect faint starlight if light were not particle-like. … WebbPhotoelectric effect. Tools. The emission of electrons from a metal plate caused by light quanta – photons. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and ...

The concept of the photoelectric effect was first documented in 1887 …
Webb13 aug. 2024 · In 1886, the photoelectric effect was observed by Heinrich Hertz, by finding that when a metallic surface is exposed to ultraviolet light, electrons are emitted from the surface. When certain metals are exposed to light, electrons are ejected from their surface. WebbThe photoelectric effect is the process that involves the ejection or release of electrons from the surface of materials (generally a metal) when light falls on them. The photoelectric effect is an important …

Webbphotoelectric effect, phenomenon in which charge particles are released from a material when it absorbs radiant energy. The photoelectric effect commonly is thought of as the ejection of electrons from the surface of a metal plate when light falls on it.
