Question

In photoelectric effect the slope of straight line graph between stopping potential v 0 and frequency of incident light v gives, charge on electrons, work function of emitter, planck's constant, ratio of Planck's constant to charge on electron

We know that E = ϕ + k E ⇒ h υ = W + e V 0 ⇒ e V 0 = h υ - W V 0 = h e υ + - W e Compare this with equation of line y = m x + c m = slope of graph = h e
