physicists have successfully captured a clear image showing individual atoms behaving like a wave. This breakthrough provides a striking demonstration of the wave-particle duality principle ...

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 ...

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.
