Unformatted text preview: velocity v (parallel to the wave vector of the EM wave). What will be the frequency of the reected wave observed by an observer at rest? Assume that perfect mirror means that the elds at the surface of the mirror have to vanish. (b) Derive the same relation using Lorentz transformations. Use the fact that ( /c, ~ k ) form a 4-vector, and rst Lorentz transform the incoming wave to the frame of the mirror, and then Lorentz transform the reected wave back to the original frame....
