Both the frequency and the intensity of a beam of light falling on the surface of photoelectric material are increased by a factor of two. This will :            
  • a)
    increase both, the maximum kinetic energy of the photo-electrons, as well as photoelectric saturation current by a factor of two.
  • b)
    increase the maximum kinetic energy of the photo-electrons by a factor greater than two and would increase the photoelectric saturation current by a factor of two.
  • c)
    increase the maximum kinetic energy of the photoelectrons by a factor greater than two and will have no effect on the magnitude of the photoelectric saturation current produced.
  • d)
    increase the maximum kinetic energy of the emitted photo-electrons by a factor of two but will have no effect on the saturation photoelectric current.  
Correct answer is option 'C'. Can you explain this answer?

Both the frequency and the intensity of a beam of light falling on the...
The maximum K.E. of ejected photoelectrons is (K.E)max = hv – φ0
If the frequency of photon is doubled, maximum kinetic energy of photon electrons becomes 

Photo current 
If intensity and frequency both are doubled. the photocurrent remains same.
