(i)[2.0]
With reference to photoelectric effect, plot a labelled graph of stopping potential ($V_s$) versus frequency ($f$) of the incident radiation.
Draw: graph of stopping potential (Vs) versus frequency (f) of incident radiation
Must show: stopping potential on vertical axis, frequency on horizontal axis, straight line with positive slope, threshold frequency intercept on frequency axis, negative intercept on potential axis
(ii)[1.0]
State how will you use this graph to determine the value of Planck’s constant.
