A) photons come out the metal when hit by a beam of electrons
B) photons come out of the nucleus of an atom under the action of an electric field
C) electrons come out of metal with a constant velocity which depends on frequency and intensity of incident light
D) electrons come out of metal with different velocities not greater than a certain value which depends upon frequency of incident light and not on intensity.
Correct Answer: D
Solution :
[d]: In photoelectric effect, kinetic energy and hence velocity is directly proportional to frequency of the incident light and independent of the intensity of light.
