transverse Doppler effect

[trans¦vərs ′däp·lər i‚fekt]
(electromagnetism)
An aspect of the optical Doppler effect, occurring when the direction of motion of the source relative to an observer is perpendicular to the direction of the light received by the observer; the observed frequency is smaller than the source frequency by the factor [1-(v / c)2]1/2, where v is the speed of the source and c is the speed of light.
