In an experiment designed to measure the speed of light, alaser is aimed at a mirror that is 44.0 km due north. A detector isplaced 129 m due east of the laser. The mirror is to be aligned sothat light from the laser refelects into the detector. (a) When properly aligned, what angle should thenormal 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 0.0050°. By how many meters (due east) will the reflected ray miss the detector?
