Vedclass · Answer

(C) Einstein's photoelectric equation is given by $K_{max} = h
u - \Phi$, where $K_{max}$ is the maximum kinetic energy of the emitted photoelectrons, $h$ is Planck's constant, $
u$ is the frequency of incident radiation, and $\Phi$ is the work function of the metal.Comparing this equation with the straight-line equation $y = mx + c$, we get $y = K_{max}$, $x = 
u$, $m = h$, and $c = -\Phi$.The slope of the graph of $K_{max}$ versus $
u$ is $h$ (Planck's constant).Since $h$ is a universal constant, the slope is the same for all metals and is independent of the intensity of the incident radiation.

According to Einstein's photoelectric equation, the graph of the kinetic energy of the emitted photoelectrons versus the frequency of incident radiation gives a straight line whose slope
