This question has statement - 1 and statement - 2 of the four choice 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 gt` v_(0) `(the threshold frequency). The maximum kinetic energy and the stopping potential are` K_(max) `and `V_(0)` respectively if the frequency incident on the surface is doubled , both the `K_(max)` and `V_(0)` are also doubled
statement - 2 : The maximum kinetic energy and the stopping potential of photoelectron emitted from a surface are linearly dependent on the frequency of incident light

A

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

B

Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.

C

Statement-1 is true, but Statement-2 is false

D

Statement-1 is false, but Statement-2 is true.
