The slope of the stopping potential \(V_0\) versus frequency \(\nu\) of the incident radiation plot is (Where symbols have their usual meaning)
- A \(e / h\)
- B \(h / c\)
- C \(h / e\)
- D \(c / h\)
Answer & Solution
Correct Answer
(C) \(h / e\)
Step-by-step Solution
Detailed explanation
\(h\nu = \phi + eV_0\) \(eV_0 = h\nu - \phi\) \(V_0 = \frac{h}{e}\nu - \frac{\phi}{e}\) Slope \( = \frac{h}{e}\)
