The following statement is correct in the case of photoelectric effect

Options

  1. AFor a given frequency of incident radiation, the stopping potential varies linearly with its intensity.
  2. BFor a given frequency of incident radiation, the photocurrent is independent of its intensity.
  3. CFor a given frequency of a incident radiation, the maximum kinetic energy of the photoelectrons is independent
  4. DFor a frequency lower than cutoff frequency, photoelectric emissions can occur if intensity of incident light

Correct answer

C. For a given frequency of a incident radiation, the maximum kinetic energy of the photoelectrons is independent

Step-by-step solution

Maximum kinetic energy of the emitted photoelectrons in photoelectric emission, depends on the frequency of incident radiation and does not depend on the intensity of incident radiation. Hence, statement given in option (c) is correct. For a given frequency of incident radiation, the photocurrent varies with the variation of intensity of incident radiation. For a given frequency of radiation, the stopping potential does not depend on the intensity of incident radiation. For a frequency lower than cut off frequency,
