The figure shows the variation of photocurrent with anode potential for four different radiations. Let f_a, f_b, f_c and f_d be the frequencies for the curves a, b, c and d respectively

Options

  1. Af_a f_b f_c f_d
  2. Bf _ a f _ b f _ c f _ d
  3. Cf _ a f _ b f _ c = f _ d
  4. Df _ a = f _ b f _ c f _ d

Correct answer

B. f _ a f _ b f _ c f _ d

Step-by-step solution

We know stopping potential is directly proportional to the frequency of the incoming radiation. This means curve ' a ' has the highest frequency and ' d ' the lowest. f_a f_b f_c f_d
