radius of curvature of spherical mirror

Did some back of the envelope calculations for the radius of curvature of our spherical mirrors, and with the help of the alternate segment theorem at this page, measuring x and y with a ruler got me r, the radius of curvature.


For the Acrilconvex mirror, 2x = 56 cm, y = 14.5 cm, so r = ( (28)^2 / 14.5 + 14.5 ) / 2 = 34.3 cm

For the Vialux mirror, 2x = 56 cm again, but y = 12 cm, so r = ( (28)^2 / 12 + 12 ) / 2 = 38.7 cm
