Dual Nature of Radiation and Matter question

2006 · Q144

NEETPhysicsDual Nature of Radiation and MatterMCQ+4 / −1
A photocell employs photoelectric effect to convert
  1. A
    change in the frequency of light into a change in the electric current
  2. B
    change in the frequency of light into a change in electric voltage
  3. C
    change in the intensity of illumination into a change in photoelectric current
  4. D
    change in the intensity of illumination into a change in the work function of the photocathode.
View written solutionFree

Correct answer: C

The photoelectric current is directly proportional to the intensity of illumination. Therefore a change in the intensity of the incident radiation will change the photocurrent also.
