In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 49.0 km due north. A detector is placed105 m due east of the laser. The mirror is to be aligned so thatlight from the laser refelects into the detector.(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?(b) Suppose the mirror is misaligned, so that theactual angle between the normal to the surface and due south is toolarge by 0.0060°. By how many meters (due east) will thereflected ray miss the detector?
