What is the slope of the graph drawn between frequency of incident light and stopping potential for a given surface?
- A \( h \)
- B \( h/e \)
- C \( eh \)
- D \( e \)
Answer & Solution
Correct Answer
(B) \( h/e \)
Step-by-step Solution
Detailed explanation
\( h\nu = eV_s + \phi_0 \) \( V_s = \left(\frac{h}{e}\right)\nu - \frac{\phi_0}{e} \) Slope \( = \frac{h}{e} \)
