The correct Answer is:
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
