Electron wave number of transitions values Transitions The Bohr model for an electron transition in hydrogen between quantized energy levels with different quantum numbers n yields a photon by emission with quantum energy: This is often expressed in terms of the inverse wavelength or "wave number" as follows: The reason for the variation of R is that for hydrogen the mass of the orbiting electron is not negligible compared to. Peaks in UV spectra tend to be quite broad, often spanning well over 20 nm at half-maximal height. Which wave has the greater velocity? That's a handy expression, and sometimes it's all you need. Compare this value with the corresponding radius in the Bohr theory. In this animation, two waves (with the same amplitude, frequency, and wavelength) are travelling in opposite directions.
