A kernel named for this behavior is used in the standard integral to create thermally averaged cross-sections. The non-classical form of this phenomenon is used by the Ives-Stilwell experiment and is known as the transverse form, while absorption resonances and spectral lines are given finite width due to this effect's namesake broadening. The magnitude of the classic version of this effect is determined by the factor of v over quantity v plus or minus v s, where v s is the propagation speed and v is the observer-frame normal source speed. For 10 points, name this effect in which the frequency of waves is altered when the source is moving relative to the observer.
