The correct graph respectively the relation between energy (E) of photoelectrons and frequency v of incident light is

A)                                                    

B)

C)                                                       

D)

Correct Answer: C

Solution :

                If using light of different frequencies a graph is plotted between the maximum kinetic energy \[{{E}_{k}}\] of the photoelectron and frequency v of light, then a straight line is obtained, according to relation \[{{E}_{k}}=h{{v}_{0}}-w\], where w is the intercept cut by straight line on negative \[{{E}_{k}}\]-axis
