Wave particle duality The photoelectric effect shows that light is made up of individual photons. Photoemissions will take place if photons have a high enough frequency and have enough energy.
The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...
Photoemission is a process during which electrons are ejected from a metal surface when exposed to electromagnetic radiation, (eg ultraviolet). If a clean, positively charged zinc plate is exposed ...
In classical optics, for instance, a brighter light has more energy, and a greater amplitude of its electromagnetic wave. But, when it comes to ejecting an electron from a material via the ...
