It is possible to detect Doppler shifts in the light emitted from each side of a rapidly spinning star. Suppose the light from a nearby star of radius 2.5 × 108 km is blue-shifted on one side of the star and red-shifted on the other side. Assume the center of mass of the star is stationary relative to Earth. If the rotational period of the star is 72 h and the star emits (unshifted) light of wavelength 525 nm, what is the wavelength of the light received on Earth from the side of the star rotating toward us?



536 nm



504 nm



530 nm



▸ 520 nm

546 nm



514 nm
