Thread: 45 dergree mirrors in Special Relativity

45 degree mirrors in Special Relativity If a moving 45 degree mirror is length contracted doesn't that mean a ray hitting it from the front will appear (from the stationary observer) to contradict the laws of reflection. ie the angle of incidence will not be equal to the angle of reflection. That is, the mirror will appear to be sitting at say something like 30 degrees from the vertical (depending on speed) but still deflect a...
