If the frequency of incident radiation (v) is increased, keeping other factors constant, the stopping potential (\(v \gt v_0\), threshold frequency)
- A increases
- B decreases
- C remains constant
- D suddenly becomes zero
Answer & Solution
Correct Answer
(A) increases
Step-by-step Solution
Detailed explanation
\(\mathrm{eV}_{\mathrm{s}}=\mathrm{h} \nu-\mathrm{W}_0\)
\(\therefore \quad\) If \(v\) increases, \(\mathrm{V}_{\mathrm{s}}\) will increase.
\(\therefore \quad\) If \(v\) increases, \(\mathrm{V}_{\mathrm{s}}\) will increase.
