In the photoelectric effect experiment, the frequency of the incident light is changed from red to blue while keeping the energy per unit area per unit time of the incident radiation fixed. What will happen to the saturation current?

Options

  1. ASaturation current for blue color light is smaller than red color light
  2. BSaturation current depends on intensity and therefore will be same for red and blue light
  3. CSaturation current does not depend on frequency and therefore will be same for red and blue light
  4. DSaturation current for blue color light is larger than red color light

Correct answer

A. Saturation current for blue color light is smaller than red color light

Step-by-step solution
