Question 275: Dual Nature of Matter and Radiation

Question

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

Accepted Answer

From the given graph,
Threshold frequency $\left(
u_0ight)$ of $A$ is less than $B$.
$	herefore \quad$ Work function $\left(h 
u_0ight)$ of A is smaller than that of B.

Answer

greater than that of B.

Answer

smaller than that of B.

Answer

same as that of B.

Answer

that no comparison can be made from the graphs.
