प्रश्न
If a spherical mirror breaks, what type of mirrors are the individual pieces?
Advertisements
उत्तर
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.
