Question

state the law of Photoelectric effect

Answer 1

Photoelectric current is directly proportional to the intensity of incident light and is independent of frequency. (c) The stopping potential and hence the maximum velocity of the electrons depends upon the frequency of incident light and is independent of its intensity.

Answer 2

1) Intensity is directly proportional to the photoelectric current.
2) frequency of light is directly proportional to the kinetic energy of electron.
