Q. The curves $(a),(b),(c)$ and $(d)$ show the variation between the applied potential difference $(V)$ and the photoelectric current $(i)$, at two different intensities of light $\left(I_{1} > I_{2}\right)$. In which figure is the correct variation shown?

Dual Nature of Radiation and Matter

Solution:

$I_{1}>I_{2}$ (given)
$\Rightarrow i_{1}>i_{2} (\because i \propto I)$
and stopping potential does not depend upon intensity. So its value will be same $\left(V_{0}\right)$.
