Question
We may state that the energy E of a photon of frequency V is E = hv, where h is Plank’s constant. The momentum P of a photon is P = h/λ where X is the wavelength of the photon. From the above statement one may conclude that the wave velocity of light is equal to - 3 x 108 m/s
- E/p
- Ep
- (E/p)2
Solution
B.
E/p
