Q. According to Einstein’s photoelectric equation, the graph between the kinetic energy of photoelectrons ejected and the frequency of incident radiation is

A)
B)
C)
D)
Explanation

(d) According to Einstein’s equation
$hv = hv_{0} + K_{\max} \Rightarrow K_{\max} = hv - hv_{0}$ on comparing it with $y = mx + c,$ it is clear that, this is the equation of straight line having positive slope $(h)$ and negative intercept $(hv_{0})$ on $KE$ axis
