i. The stable isotope of hydrogen made of a proton bound together with a neutron is called the deuteron. Given that the rest mass of a deuteron is 2.0140u , calculate the total energy of the radiation emitted when a proton and a neutron combine to form a deuteron. [4 marks] If this radiation is known to propagate at a frequency of 5.3902 x 1014HZ, find the single quantum energy of this radiation, and how many such radiation quanta are involved in the formation of the deuteron mentioned above. ii.
