In a photodiode, the value of the \(\mathrm{emf}\) produced by a monochromatic light beam is directly proportional to
  1. the barrier potential at \(p-n\) junction
  2. the intensity of light falling on the photodiode
  3. the frequency of light falling on the photodiode
  4. the voltage applied at the \(p-n\) junction

Solution

In a photodiode, the value of the emf produced by monochromatic light beam is directly proportional to the intensity of light falling on the photodiode.
