From the following graph of photo current against collector plate potential, for two different intensities of light $I_{1}$ and $I_{2}$, one can conclude :
1 $\mathrm{I}_{1}=\mathrm{I}_{2}$
2 $\mathrm{I}_{1}>\mathrm{I}_{2}$
3 $\mathrm{I}_{1} \lt \mathrm{I}_{2}$
4 Comparison is not possible
Explanation:
C Here curve of $\mathrm{I}_{2}$ intensity and curve of $\mathrm{I}_{1}$ intensity have the same frequency and hence the same stopping potential. But the number of photons striking the metal surface or the intensity of $\mathrm{I}_{2}$ curve is greater than intensity of $\mathrm{I}_{1}$ curve. $\mathrm{I}_{2}>\mathrm{I}_{1} \text { or } \mathrm{I}_{1} \lt \mathrm{I}_{2}$
