In a gas with a Maxwell-Boltzmann distribution, this effect transforms a sharp line into a Gaussian line profile. This effect
In a gas with a Maxwell-Boltzmann distribution, this effect transforms a sharp line into a Gaussian line profile. This effect is used to scan through frequencies to find resonances in gamma ray absorption in Mössbauer spectroscopy. A Galilean transformation of the phase velocity gives the equation for the classical version of this effect, while its (*) transverse form occurs due to relativistic time dilation. When the sine of the Mach angle is less than one, this effect causes wave compression in front of a wave source. Wavelength shifts caused by this effect can be red or blue based on the direction of motion of a source of light. For 10 points, name this effect that changes the frequencies of receding and advancing wave sources.
