According to Einstein's photoelectric equation, the graph between the kinetic energy of photo-electrons ejected and the frequency of incident radiation is

Options:

Answer:

Solution:

$K_{m a x} = h v - ϕ$

Comparing with equation of straight line

$y = m x + c$

$m = h,$

$c = - ϕ$

so, straight line with positive slope and negative intercept on $y -$ axis.
