#1 Question:-
Assertion:- A metallic surface is irradiated by
monochromatic light of frequency
v > V, (the threshold frequency). The
maximum kinetic energy and the
stopping potential are Kmax and V.
respectively. If the frequency incident on
the surface is doubled, both the Kmax
and V. are also 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.
A. Both are true with correct explanation
B. Both are true but not explanation
C. Assertion true but reason false
D. Both are false.
