Question

A convex lens made up of a material of refractive index n1 is immersed in medium of refractive index n2, trace the path of parallel beam of light passing through the lens when 1.N1>n2 2.N1=n2 3.N1

Answer 1

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
