We can say that the energy of a photon of frequency v is given by

E = hv,

, where h is Planck’s constant. The momentum of a photon is

p = h/\lambda ,

, where λ is the wavelength of photon. Then we may conclude that velocity of light

I

equal to:

View answer and explanation

Correct option: B

E/p

Option B (

E/p

) is correct because the velocity of light can be expressed as the ratio of energy to momentum of a photon, derived from

E=hv

and

p=h/\lambda

.
