Reading emission spectra
WebNov 4, 2014 · The discrete spectrum emitted by a H atom is a result of the energy levels within the atom, which arise from the way the electron interacts with the proton. To view the spectrum we need … WebThe energy gap of absorption is greater than that of emission. The gradient in between is termed stoke's shift. This because when the excited electron looses energy, it first gets to zero point level of excited state, emits and hits the potential well of the ground state after which it looses energy again to retire to the zero point level of the ground state.
