In an experiment designed to measurethe speed of light, a laser is aimed at a mirror that is 47.0 kmdue north. A detector is placed 120 m due east of the laser. Themirror is to be aligned so that light from the laser refelects intothe detector. (a) When properly aligned, whatangle should the normal to the surface of the mirror make with duesouth? (b) Suppose the mirror is misaligned, sothat the actual angle between the normal to the surface and duesouth is too large by 0.0030°. By how many meters (due east)will the reflected ray miss the detector?
