The refractive index of a material of a convex lens in n1. It is a immersed in a medium of refractive index n2. A parallel beam of light is incident on the lens. If n2>n1, trace the path of emergent ray .

A converging lens behaves as a diverging lens when placed in a medium of greater refractive index than that of the lens. Hence, a parallel beam of light incident on it will diverge.
