Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror.
