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 $v > {v_0}$ (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 ${K_{\max }}$ anmd ${V_0}$ 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.
Statement - $1$ is true, Statement - $2$ is true, Statement - $2$ is the correct explanation of Statement - $1$.
Statement - $1$ is true, Statement - $2$ is true, Statement - $2$ is not the correct explanation of Statement - $1$.
Statement - $1$ is false, Statement - $2$ is true.
Statement - $1$ is true, Statement - $2$ is false.
