When a parallel beam of light passes through a convex lens, after refraction it:
converges to a point on the principal axis
A convex (converging) lens is thicker at the centre than at the edges. When a parallel beam of light (rays parallel to the principal axis) passes through it, the lens bends all rays inward so that they meet at a single point on the principal axis — the principal focus (F).
This is the defining property of a converging lens: it converges parallel light to the focal point. The image formed at the focal point is real, inverted, and highly diminished (point-sized).
The correct answer is A: converges to a point on the principal axis.
