The bohr model gives a simple, but reasonably accurate, formula for the energy levels of an electron in an isolated hydrogen atom. when an electron moves from one energy level to another lower level, the difference in the energies between the two levels is emitted in a photon. what is the wavelength of the photon emitted when an electron falls from the fourth level to the first level?
