Class 12PhysicsDual Nature of Radiation and matterPhotoelectric Effect by Lenard and it's Observations
Medium"With increase in frequency of light incident, number of electrons emitted increase" - True or false?
(B) The statement is $False$.
According to the photoelectric effect, the number of photoelectrons emitted per second is directly proportional to the intensity of the incident light, not its frequency.
The frequency of the incident light determines the kinetic energy of the emitted photoelectrons, provided the frequency is above the threshold frequency $(\nu > \nu_0)$.
Increasing the frequency increases the energy of individual photons, but it does not increase the number of photoelectrons emitted.
