Question

This question has Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best 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.

Statement-1 is true, Statement-2 is true and Statement-2 is not the correct explanation of Statement-1

Statement-1 is true, Statement-2 is false

Statement-1 is true, Statement-2 is true and Statement-2 is the correct explanation of Statement-1.

Solution

hv = hv0 + kmax

kmax = hv – hv0
