The figures shows the variation of photocurrent i with anode potential V for three differential radiations. Let I_a, I_b and I_c be the intensities and f_a, f_b and f_c be the frequencies for the curves a, b and c respectively. Then

Options

  1. Af_a=f_b and I_a I_b
  2. Bf_a=f_c and I_a=I_c
  3. Cf_a=f_b and I_a=I_b
  4. Df_b=f_c and I_b=I_c

Correct answer

A. f_a=f_b and I_a I_b

Step-by-step solution

Stopping potentials for b and a are same f_a=f_b and saturation current for b and a are different I_b I_a
