Question
A ray of light from the object parallel to principal
axis of a concave lens, after refraction appears to diverge from which point on the same side of the lens?Solution
Principal focus : A ray of light from the object, parallel to the principal axis, after refraction from a convex lens, passes through the principal focus on the other side of the lens. β’ In case of a concave lens, the ray appears to diverge from the principal focus located on the same side of the lens.
