Correct option is C
When a ray of light passes through the principal focus of a convex lens, it refracts and emerges parallel to the principal axis on the other side. This is a fundamental property of convex lenses.
Information Booster:
· A convex lens is a converging lens.
· Principal focus is the point where parallel rays converge.
· Light obeys Snell’s Law during refraction.
· The path of light is reversible in a lens.
