JEE MainPhysicsDual Nature of RadiationMCQ+4 / −1

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 \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 }}

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.

A
