Photoelectric effect.svg

According to Eistein, when one photon carries an energy hf interacts with a matter . Matter will absorb photon energy to the maximum at hfo after that the difference of energy (hf -hfo) will be used in releasing electron off matter into the surrounding

Mathematicaly, we can write

To release electron off matter, speed of electron must be greater than 0
