In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 59.0 km due north. A detector is placed138 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.(a) When properly aligned, what angle must the normal to the surface of the mirror make with due south? (b) Assume the mirror is misaligned, thus that the actual angle among the normal to the surface and due south is also large by 0.0050°. By how many meters (due east) will the reflected ray miss the detector?
