Question

The energy of a photon is E=h v and the momentum of photon p=(h/λ), then the velocity of photon will be (A) E / p (B) E p (C) ((E/P))2 (D) 3 × 108 m / s

Tardigrade Admin · Accepted Answer

Momentum of photon p=(E/c) ⇒ Velocity of photon c=(E/p)

Q. The energy of a photon is $E = h v$ and the momentum of photon $p = \frac{h}{λ}$ , then the velocity of photon will be

$E / p$

$Ep$

$(\frac{E}{P})^{2}$

$3 \times 1 0^{8} m / s$

Momentum of photon $p = \frac{E}{c}$
$\Rightarrow$ Velocity of photon $c = \frac{E}{p}$

Q. The energy of a photon is E=hv and the momentum of photon p=λh​, then the velocity of photon will be

E/p

Ep
