In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 54.0 km due north. A detector is placed107 m due east of the laser. The mirror is to be aligned so thatlight from the laser refelects into thedetector. (a) When properly aligned,what angle should the normal to the surface of the mirror make withdue south? (b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.0020°. By how many meters (due east) will the reflected ray miss the detector?
