angle deviation of the light wave as it passes through a prism seems to be inversely related (looks like a 1/x graph) to its wavelength. So my question, why?

My guess is that the deflected path is shorter than the undeflected by cos A, where

0 < A < 90

and the bigger wavelength is, the longer the path it can travel and thus a bigger wavelength corresponds to a longer path x cos A?
