Kinetic energy with which the electrons are emitted from a metal surface due to photo-electric effect is
  1. Dependent of the intensity of illumination
  2. Directly proportional to the intensity of illumination
  3. Inversely proportional to the intensity of illumination
  4. Dependent on the frequency of light

A
Dependent on the frequency of light
B
Directly proportional to the intensity of illumination
C
Inversely proportional to the intensity of illumination
D
Dependent of the intensity of illumination
Solution
Verified by Toppr

Kinetic energy = incident energy - work function
=hνhν0
So, K.E. is dependent on frequency of light.
