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. `E p`
D. `(E/p)^(2)`

Answer

B

Explanation

`C=lambda.v=h/p.E/h=E/p`
