This question has Statement - 11 and Statement - 22 . Of the four choices given after the statements, choose the one that best describes the two statements.

Statement - 11 : A metallic surface is irradiated by a monochromatic light of frequency v > {v_0} (the threshold frequency). The maximum kinetic energy and the stopping potential are Kmax⁡{K_{\max }} and V0{V_0} respectively. If the frequency incident on the surface is doubled, both the Kmax⁡{K_{\max }} anmd V0{V_0} are also doubled.
Statement - 22 : The maximum kinetic energy and the stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequency of incident light.

Multiple Choice Options

  • A Statement - 11 is true, Statement - 22 is true, Statement - 22 is the correct explanation of Statement - 11 .
  • B Statement - 11 is true, Statement - 22 is true, Statement - 22 is not the correct explanation of Statement - 11 .
  • C Statement - 11 is false, Statement - 22 is true.
  • D Statement - 11 is true, Statement - 22 is false.

Step-by-Step Verified Solution

By Einstein photoelectric equation,

Kmax⁡=eV0=hv−hv0{K_{\max }} = e{V_0} = hv - h{v_0}

When vv is doubled, Kmax⁡{K_{\max }} and V0{V_0} become more than double.
