A proton of mass ,mp, (given in data) is confined in a very-deep Square-well potential with L= 1 femto meter.
(I) Sketch a diagram to show the allowed energy levels of the proton inside the well.
(ii) Estimate ground-state energy of the proton.
(iii) If the proton somehow gets excited to n= 3 level and then jumps back to n=1 determine the energy and wavelength of the emitted gamma-ray photon.
