Question

In a photoelectric experiment, the stopping potential V s is plotted against the frequency v of the incident light. The resulting curve is a straight line which makes an angle θ with the v-axis. Then t a n θ will be equal to (Here E 0 = work function of the surface), h e, e h, - ϕ e, e h ϕ

MARKS App · Accepted Answer

E K = h v - ϕ e V s = h v - ϕ V s = h v e - ϕ e …(i) y = m x + C …(ii) Comparison of equation (i) and (ii) shows that the slope i.e., t a n θ will be equal to h e . m ( S l o p e ) = t a n θ = h e .
