Question

Consider the following statements –

(1) The energy E of a photon of frequency ν is E = hν, where h is Planck's constant

(2) The momentum p of a photon is p = h/λ, where λ is the wavelength of the photon

From the above statements one may conclude that the wave velocity of light is equal to -

• A. 3 × 10⁸ m/sec
• B. E/p
• C. Ep
• D. (E/p)

Answer 1

Answer: (B)

E/p

Answer 2

E = hν =

p =

So, == c
