For a photosensitive material, work function is ' W ₀ ' and stopping potential is ' V '. The wavelength of incident radiation is ( h = Planck's constant, c= velocity of light, e= electronic charge)

Options

  1. Ah ^2 c ^2 ~W ₀+ eV
  2. Bhc W ₀
  3. ChcV W ₀
  4. Dhc W ₀+ eV

Correct answer

D. hc W ₀+ eV

Step-by-step solution

From Einstein's photoelectric equation, we can write, array ll & eV = hc - W ₀ & hc = W ₀+ eV & = hc ~W ₀+ eV array
