The given graph shows the variation of photo-electric current (I) versus applied voltage (V) for two different photosensitive materials and for two different intensities of the incident radiation. Identify the pairs of curves that correspond to different materials but same intensity of incident radiation.

Curve 1 and 3 and curves 2and 4 corresponds to different materials.

For a given frequency of incident radiation the stopping potential is independent of intensity of light. As the pair of curves: 1and3 and 2and 4 have different stopping potential so those materials are different.
