Consider the two following statements AA and BB, and identify the correct choice given in the answers : (A) In photovoltaic cells the photoelectric current produced is not proportional to the intensity of incident light. (B) In gas filled photoemissive cells, the velocity of photoelectrons depends on the wavelength of the incident radiation.

Options

  1. Aboth AA and BB are true
  2. Bboth AA and BB are false
  3. CAA is true but BB is false
  4. DAA is false but B\mathrm{B} is true

Correct answer

D. AA is false but B\mathrm{B} is true

Step-by-step solution

In photovoltaic cells the photoelectric current produced is proportional to the intensity of incident light, so statement AA is false. The velocity of photoelectrons depends on the maximum kinetic energy of photoelectrons, which depends on the frequency and hence on the wavelength of incident radiation, so statement BB is true.
