Light of energy E falls normally on a metal of work function E 3 . The kinetic energies K of the photo electrons are

Options

  1. AK= 2 E 3
  2. BK= E 3
  3. C0 K 2 E 3
  4. D0 K E 3

Correct answer

C. 0 K 2 E 3

Step-by-step solution

Given, work function, ₀=E / 3 According to Einstein's photoelectric equation, K_ =E- ₀=E- E 3 K_ = 2 E 3 Kinetic energy lies between 0 to 2 E / 3 .
