A light of wavelength ' ' and intensity ' I ' falls on photosensitive material. If ' N ' photo electrons are emitted, each with kinetic energy ' E ', then

Options

  1. AE I, N
  2. BE I , N I
  3. CE I , N 1
  4. DE 1 , N I

Correct answer

D. E 1 , N I

Step-by-step solution

Intensity is proportional to the number of photons, since each photon interacts with one electron, the number of electron N I . Energy of photon is h c , hence it is inversely proportional to the wavelength.
