(a) (b) Determine the volume density and area density on the (1 0 0) plane of a body- center cubic cell with lattice constant of 5 Å. (i) (ii) If the electron in a hydrogen atom jumps from energy level n = 2 to energy level n = 1, explain if a photon is absorbed or emitted. Find the wavelength of the photon given that En = -13.6/n² eV. Determine all the energy sublevels for n = 2.
