When the photon of light is incident on the metal surface, electron absorb the light which can be ejected from the surface of the metal used. This phenomenon is called photo electric effect.
The factors on which it depends are
Intensity of light
Frequency of photoelectron
Final Answer:
When the photon of light is incident on the metal surface, electron absorb the light which can be ejected from the surface of the metal used. This phenomenon is called photo electric effect.
It depend on the intensity of the light and the frequency of photoelectron.
