Question

Study the following graphs between photoelectric current (i) vs. collector potential (V) for three different radiations a, b, and c of frequencies f_a, f_b, f_c respectively with corresponding intensities I_a, I_b, and I_c respectively falling on a given photosensitive surface. 

 

Select the correct option.

A. f_a ≠ f_b ; I_a = I_b 

B. f_b = f_c ; I_b = I_c 

C. f_a = f_b ; I_a ≠ I_c 

D. f_b ≠ f_c ; I_b ≠ I_c

Answer 1

Correct option is : C. f_a = f_b ; I_a ≠ I_c
