Which of the following can make a parallel beam of light when light from a bulb falls on it?(a) concave mirror as well as concave lens (b) convex mirror as well as convex lens(c) concave mirror as well as convex lens (d) convex mirror as well as concave lens
(c) Concave mirror as well as Convex lens
Explanation
When an object is placed at the focus of a convex lens, the refracted light rays are always parallel to each other and to the principal axis.
When an object is placed at the focus of a concave mirror, the reflected light rays are always parallel to each other and to the principal axis.
