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
- A \(f_a=f_b\) and \(I_a \neq I_b\)
- B \(f_a=f_c\) and \(I_a=I_c\)
- C \(f_a=f_b\) and \(I_a=I_b\)
- D \(f_b=f_c\) and \(I_b=I_c\)
Answer & Solution
Correct Answer
(A) \(f_a=f_b\) and \(I_a \neq I_b\)
Step-by-step Solution
Detailed explanation
Stopping potentials for \(b\) and \(a\) are same \[ \therefore \quad f_a=f_b \] and saturation current for \(b\) and \(a\) are different \[ \therefore \quad I_b \neq I_a \]
