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

Options

  1. Agreater than that of B.
  2. Bsmaller than that of B.
  3. Csame as that of B.
  4. Dthat no comparison can be made from the graphs.

Correct answer

B. smaller than that of B.

Step-by-step solution

From the given graph, Threshold frequency (v₀ ) of A is less than B . Work function (h v₀ ) of A is smaller than that of B.
