(A) Comparing Einstein's photoelectric equation $\frac{1}{2}mv_{\max}^2 = hf - \phi_0$ with the linear equation $y = mx + c$,where $y = \frac{1}{2}mv_{\max}^2$,$x = f$,$m = h$,and $c = -\phi_0$.The slope of the graph is Planck's constant $h$,which is a universal constant and is independent of the nature of the metal or the intensity of the incident radiation.
