Question

For photo - electric effect with incident photo wavelength `lambda` the stopping is `V_(0)` identify the correct variation(s) of `V_(0)` with `lambda and 1 // lambda`
A.
B.
C.
D.

Answer 1

Correct Answer - A::C
we know that `( hC)/(lambda) W = eV _(0) rArr (hc)/(e lambda) - (W)/€ = V_(0)`
for `V_(0) vesos (1)/(lambda)` we get a straight line with negative slop and positive intercap
for `V_(0) vesus lambda` , we get a hydrogen . As with decrease `V_(0)` increases
(a) and (c ) is correct option
