Photoelectric effect
The photoelectric effect is a phenomenon in physics. The effect is based on the idea that electromagnetic radiation is made of a series of particles called photons. When a photon hits an electron on a metal surface, the electron can be emitted. The emitted electrons are called photoelectron.A photon is like a tiny blob of pure energy. In the photoelectric effect, an electron is hit by a wandering blob of energy and is so excited that it breaks its bond with the atom to which it is held.
photon energy = work function + electron kinetic energy
The equation is:
hν = Ee + W
Where:
h: Planck's constant
ν: Frequency of the incident light
Ee: Energy of the electron
W: the work function of the material
