We may state that the energy E of a photon of frequency `nu` is `E =hnu`, where h is a plank's constant. The momentum p of a photon is `p=h//lambda` where `lambda` is the wavelength of the photon. From the above statement one may conclude that the wave velocity of light is equal to

Options

A. `3xx10^(8)ms^(-1)`
B. `(E )/(p)`
C. `Ep`
D. `((E )/(p))^(2)`

Answer

B

Explanation

`C= lambda.v=(h)/(p).(E)/(h)=(E)/(P)`
