The work function of a metal is 3.4 eV . If the frequency of incident radiation is increased to twice, then the work function of the metal becomes

Options

  1. A3.4 eV
  2. B7.2 eV
  3. C6.8 eV
  4. D1.7 eV .

Correct answer

A. 3.4 eV

Step-by-step solution

The work fuction of a metal is an inherent property of the metal itself and it does not change with the frequency of the incident light.
