According to Einstein’s photoelectric equation, the plot of the kinetic energy of the emitted photo electrons from a metal vs the frequency of the incident radiation gives a straight line whose slope:

A $Depends on the nature of the metal used$
B $Depends on the intensity of the radiation$
C $Depends both on the intensity of the radiation and the metal used$
D $Is the same for all metals and independent of the intensity of the radiation$

Solution & Step-by-step Explanation

Einstein's photoelectric equation is K_{ma x} = h ν - ϕ .Comparing this with the equation of a straight line y = m x + c : y = K_{ma x} x = ν Slope m = 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.
