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