Which of the following options represent the variation of photoelectric current with property of light shown on the x-axis?

  1. A only

  2. A and C

  3. A and D

  4. B and D

Correct answer · Option 3

A and D

Explanation

Photoelectric current is directly proportional to the intensity of light (Graph A). It depends on the frequency of light only if it exceeds the threshold frequency, showing a linear increase above threshold (Graph D). Thus A and D are correct.
