If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line at a wavelength of 560 nm, what difference in wavelength (in nm GM should you expect between the opposite edges of the rings? (Hints: The radius of the edge the A ring is 136,500 km. Use the formula for orbital velocity, V. = V O and the formula for Doppler shift, nm
