Question

Direction : The question has Statement 1 and Statement 2. Of the four choices given after the statements, choose the one that describes the two statements.
Statement 1 : A metallic surface is irradiated by a monochromatic light of frequency v>v0 (the threshold frequency). The maximum kinetic energy and the stopping potential are Kmax and V0 respectively. If the frequency incident on the surface is doubled, both the Kmax and V0 are also doubled.
Statement 2 : The maximum kinetic energy and the stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequency of incident light.

Solution

The correct option is C Statement 1 is False, Statement 2 is True.
KEmax=hμhμ0
e×Δv=hμhμ0
V0=hμehμ0e
μ is doubled
KEmax=2hμhμ0
V0=(ΔV)=2hμehμ0e
V0V0 may not be equal to 2
V=hμehμ0e
So, the answer is option (D).
