The factor y in the Doppler formula (15.64), which can be ascribed to time dilation, means that even when 0 = 90 there is a Doppler shift. (In classical physics there is no Doppler shift when 6 = 90 and the source has zero velocity in the direction of the observer.) This transverse Doppler shift is t
