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 \[\upsilon >{{\upsilon }_{0}}\] (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 photoelectrons emitted from a surface are linearly dependent on the frequency of incident light. [AIEEE 2011]

A) Statement-1 is false, Statement-2 is true

B) Statement-1 is true, Statement-2 is false

C) Statement-1 is true, Statement-2 is true and Statement-2 is a correct explanation for Statement-1

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