A star is found to be moving across our sky at a small fraction of the speed of light, in a direction at right angles to the line from the star to the Earth. The Doppler shift of the spectrum of the light from this star is

(a)   zero for all wavelengths, because the star is moving perpendicular to the line of sight.
(b)   small, since the star's speed is small, but it is not zero. The shift is greater for red light than for blue light.
(c)   small, but not zero, and greater for the more energetic blue photons than for the less energetic red photons.
