freely on a bench with scale attached. Byusing verniers on these stands very close results can beobtained. A very useful exercise in connection with thisexperiment is the determination of the radii of curvature ofsmall mirrors, such as are used in reflecting telescopes, orgalvanometers.

By the law of reflection, the angle MAL is equal to the angleMAN, and therefore also equal to the angle PAC. xPAC sin PAC sinACP sinACP PC = PCPA PA Now limit the ray PA by supposing it incident close to B,the point…
