$E/p$

Vedclass · Answer

(A) The energy of a photon is given by $E = h
u$ and the momentum is given by $p = \frac{h}{\lambda}$.Since the velocity of a photon is $c = 
u \lambda$,we can express the energy as $E = h \left( \frac{c}{\lambda} ight) = \frac{hc}{\lambda}$.Substituting the expression for momentum $p = \frac{h}{\lambda}$ into the energy equation,we get $E = pc$.Rearranging this equation to solve for the velocity $c$,we obtain $c = \frac{E}{p}$.Thus,the velocity of the photon is $E/p$.

The energy of a photon is $E = h\nu$ and the momentum of a photon is $p = \frac{h}{\lambda}$. The velocity of the photon is:
