Verified by Toppr
The correct option is B Convergent lens After completely immersed in water this bag will behave as convergent lens because the material of the lens is the same but the outside materials density is increased. This leads to the converging of the rays.

Q3
A lens is a piece of transparent material with two refracting surfaces such that at least one is curved and refractive index of its material is different from that of the surroundings. A thin spherical lens with refractive index greater than that of surroundings behaves as a convergent or convex lens, i.e., converges parallel rays if its central (i.e., paraxial) portion is thicker than marginal one. However if the central portion of a lens is thinner than marginal, it diverges parallel rays and behaves as divergent or concave lens. show this and classify identify convergent and divergent lenses.
