If the momentum of a photon is $p$,then its frequency is:

The momentum of a photon of energy $1 \, MeV$ in $kg \, m/s$ will be:

$A$ photon of frequency $v$ has a momentum associated with it. If the speed of light is $c$,then the momentum is .......

When an $X$-ray photon collides with a proton,its frequency:

Monochromatic light of frequency $6 \times 10^{14} \,Hz$ is produced by a laser. The power emitted is $2 \times 10^{-3} \,W$. How many photons per second on an average are emitted by the source? (Given $h = 6.63 \times 10^{-34} \,Js$)

Assertion: The energy $(E)$ and momentum $(p)$ of a photon are related by $p = E/c$.
Reason: The photon behaves like a particle.
