Question

If a spherical mirror breaks, what type of mirrors are the individual pieces?

Short/Brief Note
Advertisements

Solution

After the breakdown of the spherical mirror, each piece of the mirror is the same type of original mirror (concave/convex), as the reflective background and curvature have no differences in radius.
