according to einsteins photoelectric equation the plot of

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

A. depends both on the intensity of the radiation and the metal used

B. depends on the intensity of the radiation

C. depends on the nature of the metal used

D. is the same for the all metals and independent of the intensity of the radiation

Answer : is the same for the all metals and independent of the intensity of the radiation

Solution :
From Equation $$K.E. = hv - \phi $$
slope of graph of $$K.E\,\& \,v$$ is $$h$$ (Plank's constant)
which is same for all metals
