If the frequency of the incident light is doubled from vi to vf = 2vand the distance of the source of light from the photoelectric plate is reduced from which of the following statement(s) is (are) not correct? [ vi, vf > v0, where v0 is cut off frequency]
  • a)
    If > I[I denotes saturation current]
  • b)
    |Vf| >|Vi| [V denotes the stopping potential]
  • c)
     denotes the maximum kinetic energy of the photoelectrons]
  • d)
    denotes the work function of the photoelectric material]
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
If the frequency of the incident light is doubled from vi to vf = 2via...
Since reducing distance would increase the intensity of the incident light, the saturation current would increase.
i.e., If>Ii
The magnitude of the stopping potential would increase since frequency has doubled :
|Vf|>|Vi|
Work function is a property of the photo electric material concerned. Since the plate is kept unchanged.
