This effect was confirmed in an experiment performed by Buys Ballot, and a relativistic form of this effect was used in the Ives-Stilwell experiment.
This effect was confirmed in an experiment performed by Buys Ballot, and a relativistic form of this effect was used in the Ives-Stilwell experiment. Another experiment using this effect to study light waves was done by Hippolyte Fizeau. A change in the wavelength of light moving away from a viewer is called red shift, or the "relativist" form of this effect. For 10 points, identify this effect, a change in the frequency of a wave for a moving object, which accounts for a pitch change in a moving siren.
