Law of light emission
1) The rate of emission of light electrons from the surface of a metal is proportional to the intensity of light falling on the surface of the metal.
2) The maximum speed energy of the emitting light electrons does not depend on the intensity of incident light.
3) The maximum speed energy of light electrons increases with the increase of incident light allocation.
4) If the frequency of incident light is less than a minimum allocation, no electrons are emitted from the surface of the metal. This minimum distribution is called the sill level. The value of the sill is different for different metals.
5) There is no time lag between light falling on the metal surface and electrons being emitted from the metal surface, ie electrons are emitted as soon as the light falls on the metal surface.
