The curve drawn between velocity and frequency of photon in vacuum will be a                                               [MP PET 2000]

A)            Straight line parallel to frequency axis

B)            Straight line parallel to velocity axis

C)            Straight line passing through origin and making an angle of 45o with frequency axis

D)            Hyperbola

Correct Answer: A

Solution :

                   Velocity of photon (i.e. light) does not depend upon frequency. Hence the graph between velocity of photon and frequency will be as follows
