WebΔλ = 17 * (12,000,000 / 300,000,000) = 0.68. Since Δλ is the change in lambda, this would be the amount that the radio wave is shifted. So the answer to this question is simply 0.68 mm.

WebSurface brightness. In astronomy, surface brightness (SB) quantifies the apparent brightness or flux density per unit angular area of a spatially extended object such as a galaxy or nebula, or of the night sky background. An object's surface brightness depends on its surface luminosity density, i.e., its luminosity emitted per unit surface area.
