The above reprt the graph electron energy against the frequency of the radiation incident on a metal surface. lnterprete the;
(i) slope of the graph;
(ii) intercept, OC;
(iii) intercept, OK.
Explanation
(i) Slope represents the Planck's constant, h.
(ii) Intercept OC represents the work function of the metal.
(iii) The intercept OK represents the threshold frequency of the radiation.
