Laws of photoelectric
emission :-
1.
The incident radiation should posses the minimum
frequency required to pull the electron from the surface of metal known as
threshold frequency.
2.
For the incident radiation with the threshold
frequency. The photoelectric current increases with increase in it's intensity.
3.
The velocity of emitted electron and energy of
emitted electron is independent of the intensity of the light and depends only
in the frequency of the incident light and nature of the metal,
4.
The maximum velocity (Vmax) and stopping potential
are independent of the incident light but are directly proportional to the
frequency of incident radiation.
