A nucleus makes a transition from one permitted energy level to another level to lower energy. Name the region of the electromagnetic spectrum to which the emitted photon belongs. What is the order of its energy in electron volts? Write four characteristics of nuclear force.                

Answer:

                In a nuclear transition, short wavelength electromagnetic waves called gamma rays are emitted. The emitted photons have energy of the order of million electron volts. Characteristics of nuclear forces are : (i) short range,                  (ii) very strong, (iii) charge independent, and (iv) non-central forces.
