Dual Nature of Radiation and Matter
In photoelectric effect, the number of photo-electrons emitted is proportional to
velocity of incident beam
frequency of incident beam
intensity of incident beam
work function for cathode material
C.
intensity of incident beam
By increasing the intensity of incident beam, the number of emitted photo-electrons can be increased. Hence, number of photo-electrons emitted is proportional to the intensity of the incident beam.
