MHT CET Physics question

According to Einstein's photoelectric equation, the graph of KE of the photoelectron emitted from the metal versus the frequency of the incident radiation gives a straight line graph, whose slope

(A)depends on the intensity of the incident radiation
(B)depends on the nature of the metal and also on the intensity of incident radiation
(C)is same for all metals and independent of the intensity of the incident radiationCorrect
(D)depends on the nature of the metal

Answer: (C)

Solution

is a straight line of slope , a universal constant; the slope does not depend on intensity (a,
