Question

the radius of curvature of each Face Of biconvex lens made of grace glass of refractive index 1.5 is 30 cm calculate the power of the lens in water effects of the water is 1.33

Answer 1

The lens will behave as a diverging lens when light rays enter from air to lens. The refractive of lens is lesser than the refractive index of the medium i.e., water. So. The lens will behave as a converging lens when light rays travel from lens to water.I hope this answer is helpful to you
