The photoelectric threshold for a certain metal surface is 360 Å . If the metal surface is irradiated by a wavelength of 1100 Å , the kinetic energy of the emitted photoelectrons is

Options

  1. A1 . 1   eV
  2. B2   eV
  3. C2 . 3   eV
  4. D0

Correct answer

D. 0

Step-by-step solution

Given that Wavelength of incident light λ = 1100   Å Threshold wavelength λ = 360   Å Here λ > λ th , so photo electric effect not produce
