Answer with Explanation:
We are given that
Momentum of photon=

a. We have to find the energy of this photon.
Speed of photon=

We know that
Momentum=p=

Where
h=
J-s=Plank's constant
Wavelength of photon


m


J
Hence, the energy of photon=
J
B.Energy of photon in electron volt=

Energy of photon=

C.Wavelength of photon =
