Maximum kinetic energy of a photoelectric varies with the frequency $\left(f\right)$ of the incident radiation as
NTA AbhyasNTA Abhyas 2022
Solution:
From Einstein's photoelectric equation, we have
$K_{m a x}=hf-\phi_{0}$ .....(i)
Here, $\phi_{0}=$ work function of the surface
$=$ constant
From Equation. (i), graph of $K_{m a x} \, v/sf$ is
