For a given photosensitive material, the stopping potential \( V_0 \) varies with the frequency of incident radiation as
- A inversely proportional to frequency
- B linearly with frequency
- C independent of frequency
- D exponentially with frequency
Answer & Solution
Correct Answer
(B) linearly with frequency
Step-by-step Solution
Detailed explanation
\(K_{max} = h\nu - \phi\) \(eV_0 = h\nu - \phi\) \(V_0 = \frac{h}{e}\nu - \frac{\phi}{e}\) linearly with frequency
