Described by the equation delta f equals negative v sub s comma r divided by lambda naught, this effect explains red shift and blue shift, and it can be observed in the pitch change of an ambulance siren.
The Ives-Stilwell experiment utilized one variety of this effect to demonstrate part of relativity theory. Hippolyte Fizeau independently discovered a version of this effect which affects electromagnetic waves. Described by the equation delta f equals negative v sub s comma r divided by lambda naught, this effect explains red shift and blue shift, and it can be observed in the pitch change of an ambulance siren. For ten points, identify this effect which occurs when the source of a wave changes relative to an observer, which changes the frequency.
