This is a "test your physics intuition" puzzle. When light reflects from a stationary mirror, we know that (1) the angle of reflection equals the angle of incidence, and (2) the frequency of the reflected light equals the frequency of the incident light, i.e. there is no Doppler shift. Does any of this change if the mirror is moving with a velocity parallel to its surface? Gene __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
