Assertion :- A metallic surface is irradiated by monochromatic light of frequency \( vv_{0} \) (the threshold frequency). The maximum kinetic energy and stopping potential are \( \mathrm{K}_{\max } \) and \( \mathrm{V}_{\mathrm{S}} \) respectively. If the frequency of incident on the surface is doubled, both \( \mathrm{K}_{\max } \& \mathrm{~V}_{\mathrm{s}} \) are more than _ doubled.
Reason :- The maximum kinetic energy and the
- stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequency - of incident light.
_ (1) A
(2) \( \mathrm{B} \)
(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
