Q)
(chatquestion)...If the surface of a metal succesively exposed to
37.
350 nm and
radiation of/wavelength 2,
2, = 450nm the maximum velocity of
photoelectrons will differ by a factor of 2. The
work function of this metal is :-
2.
(1) 2.8 × 10-20
(2) 6.1 x 10-17 J
(3) 3.2 × 10-18
(4) 4.0 x 10-19 J
