4. The nuclear potential energy that binds protons and neutrons in a nucleus is often approximated by a square well. Imagine a proton confined in an infinitely high square well of length 1 x 10-¹4 m, a typical nuclear diameter. Assuming the proton makes a transition from the first excited state n = 2 to the ground state n = 1, calculate (a) the energy and the wavelength of the emitted photon. (b) Identify the region of the electromagnetic spectrum to which this wavelength belongs. (The mass of a proton is mp = 1.67 x 10-²7 kg) (25 Marks)
