Dear Student

Convex lenses are converging lenses. When parallel lines are directed on it they converge at the focal point. The image formed by the convex lens is magnified.

Concave lenses are diverging lens. Parallel rays falling on it diverge from a point and appears to come from apoint called focal point. The image formed by it is diminished,
