The figure shows a plot of photo current versus anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement?

AIPMT 2009 Physics - Dual Nature of Radiation and Matter Question 48 English
  1. A
    Curves (a) and (b) represent incident radiations of same frequency but of different intensities.
  2. B
    Curves (b) and (c) represent incident radiations of different frquencies and different intensities.
  3. C
    Curves (b) and (C) represent incident radiations of same frequency having same intensity.
  4. D
    Curves (a) and (b) represent incident radiations of different frequencies and different intensities
View written solutionFree

Correct answer: A

Retarding potential depends on the frequency of incident radiation but is independent of intensity.
