An object O is placed at the location shown in front of
a convex spherical mirror. Use ray tracing to determine the
location and size of the image in the mirror. As you work, keep in
mind the following properties of principal rays:
A ray parallel to the axis, after reflection, passes through the
focal point F of a concave mirror or appears to come from
the (virtual) focal point of a convex mirror.
A ray through (or proceeding toward)...

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.
