The stopping potential as a function of frequency of incident radiation is plotted for two different photoelectric surfaces A and B. The graph shows that the work function of A is
- A greater than that of B.
- B smaller than that of B.
- C same as that of B.
- D that no comparison can be made from the graphs.
Answer & Solution
Correct Answer
(B) smaller than that of B.
Step-by-step Solution
Detailed explanation
From the given graph,
Threshold frequency \(\left(v_0\right)\) of A is less than B .
\(\therefore \quad\) Work function \(\left(h v_0\right)\) of A is smaller than that of B.
Threshold frequency \(\left(v_0\right)\) of A is less than B .
\(\therefore \quad\) Work function \(\left(h v_0\right)\) of A is smaller than that of B.
