Explanation:
(a) It is known that relation between energy and mass is as follows.
where, E = energy
m = mass
c = speed of light = m/s
As it is given that mass is kg. So, putting the given values into the above formula as follows.
=
=
Therefore, we can conclude that the energy produced by the reaction between one electron and one positron is .
(b) When gamma ray photons are produced then they will have the same frequency. Relation between energy and frequency is as follows.
E = ..... (1)
where, h = plank's constant =
= frequency
Also, ........ (2)
Hence, equating equations (1) and (2) as follows.
=
So,
=
=
Thus, we can conclude that the frequency is .
