The magnification produced by a spherical lens and a spherical mirror is + 2.0.
(a) The lens and mirror are both concave
(b) The lens and mirror are both convex
(c) The lens is convex but the mirror is concave
(d) The lens is concave but the mirror is convex
उत्तर
The lens is convex but the mirror is concave.
Because both concave mirror and convex lens have positive magnification.
