(question by Henry Greenside, Duke Physics)

Consider three identical square planar mirrors that are gluedtogether to form three adjacent sides of a cube meeting at acorner, with the mirrored sides all facing towards each other. Showthat these mirrors act as a universal reflector that sends lightback to its source: any light beam entering this arrangement ofmirrors will leave parallel and opposite to its originaldirection.

If you look into such a corner reflector, what kind of image willyou see of your face?

Note: Such corner reflectors were left on the surface of the moonby Apollo astronauts and were used in ranging experiments, in whichlaser beams from an observatory on Earth were bounced off thesurface of the Moon and returned to the observatory, with the timeof transit being measured. This enabled the distance from the Earthto the Moon to be measured with high accuracy which has been usefulin testing the theory of general relativity and also forinvestigating the geology and origin of the Moon.

Your friend, an artist, has been thinking about an interestingway to display a new wind sculpture she has just created. In orderto create an aural as well as visual effect, she would like to usethe wires needed to hang the sculpture as a sort of a stringinstrument.

She decides that with two wires and some luck, the wires will sounda C-major dyad (C - 262Hz, G - 392 Hz) when the wind blows (note: Adyad is part of a chord.). Her basic design involves attaching apiece of wire from a hook on the ceiling, attaching a second pieceof wire to the first wire, and then hanging the 50 pound sculpturefrom the second wire. Your friend tells you that she has beensuccessful in hanging the sculpture but not in "tuning" the sound.Desperate for success, she knows you are taking physics and asksfor your help. Before you tackle the analysis, you use yourknowledge of waves to gather some more information. You takesamples of the wires back to your lab and measure their linear massdensities and find them to be 5.0 g/m and 8.3 g/m. What is youradvice? Assume that the junction of the two wires can'tvibrate.
