Q156 / 160 · TS EAMCET 2023 (14 May Shift 2) · Physics

The graph given in the figure shows the variation of photo current (I) and the applied voltage (V) for two different materials and for two different intensities of the incident radiations. Then the curves which represent the same material are Figure

  • A
    1 and 3
  • B
    1 and 4
  • C
    2 and 3
  • Correct answer
    D
    3 and 4

Solution

The pair of materials 1 \& 2 and $3 \& 4$ have same stopping potential so $1 \& 2$ or $3 \& 4$ represents same material.

Hence, the correct answer is option: 'D'.
