In the Mossbauer effect, this phenomenon is responsible for the suppression of nuclear recoil during photon emission, and its second-order, or transverse, variety exists only in relativistic systems.
In the Mossbauer effect, this phenomenon is responsible for the suppression of nuclear recoil during photon emission, and its second-order, or transverse, variety exists only in relativistic systems. Responsible for the characteristic red shift observed for receding galaxies, this phenomenon is the frequency change in a signal between a source and a receiver that are moving relative to each other. For 10 points, name this effect whose acoustic version manifests as the sudden pitch change heard in a passing train whistle.
