The motion of a transparent medium influences the
(b) Show that for v << c, the expression from part (a) becomes, to a good approximation,
(c) Argue for or against the view that we should expect the result to be u = (c/n) + v according to the Galilean transformation and that the presence of the term −v/n2 represents a relativistic effect appearing even at “nonrelativistic’’ speeds. (d) Evaluate u in the limit as the speed of the water approaches c.
