Inverse Doppler effect

Inverse Doppler effect

While the usual Doppler effect means that the frequency increases if the observer approaches the source - and decreases as they move away from each other - the theorists have speculated, since 1943, about the possibility that these rules may be interchanged. That would create an inverse Doppler effect.

An experiment that claimed to have detected this effect was conducted by Nigel Seddon and Trevor Bearpark in Bristol, United Kingdom in 2003 [citation
