## In This post you will get answer of Q.

According to Einstein’s photoelectric equation, the graph of kinetic energy of the photoelectron emitted from the metal versus the frequency of the incident radiation gives a straight line graph, whose slope

Solution:

## According to Einsteins photoelectric equation Maximum kinetic energy, $K_{max}=hupsilon – phi_{0}$

where, $h$ = Planck’s constant

$upsilon$= Frequency of incident light

$phi_{0}$= Work function of a metal

Compare it with the equation of straight line

$y=mx+c$

we get, slope of the graph = $h$
