The relativistic version of this effect has a coefficient of proportionality equal to the square root of one minus beta divided by one plus beta, while the classical version is simply described in terms of the velocities of the source and observer.
Non-invasive measurement of blood flow is possible using an ultrasound and a laser via the photoacoustic version of this effect, while another form of this effect was detected using a Dempster-type canal ray tube and a photographic plate. Binary pulsars display a quadratic form of it known as the Shklovskii effect, and in addition to the Ives-Stillwell experiment's detection of the transverse form of this effect, this effect is the principle behind Chu, Cohen-Tannoudji, and Philips laser-cooling apparatus. The relativistic version of this effect has a coefficient of proportionality equal to the square root of one minus beta divided by one plus beta, while the classical version is simply described in terms of the velocities of the source and observer. For 10 points, name this effect in which the percieved wavelength of a wave changes with motion.
