Solution

The correct option is B
False

As per our analogy, the speed of light increases in the lens instead of being slowed down. So, the convex lens diverges the light instead of converging it.

Imagine a concave lens placed in a liquid whose optical density is equal to that of the liquid. What will be the nature of the lens?

Q. A lens that has convex surface at one side and concave surface at another side behaves as :

a) convergent lens when the radius of curvature of convex surface is greater than that of concave surface.
b) divergent lens when the radius of curvature of concave surface is greater than that of convex surface.
c) convergent lens when the radius of curvature of convex surface is less than that of concave.
d) divergent lens when the radius of curvature of concave surface is less than that of convex surface.

Q. A convex lens is made of a material having refractive index

1 \cdot 2

. Both the surfaces of the lens are convex. If it is dipped into water (

μ = 1 \cdot 33

), it will behave like
(a) a convergent lens
(b) a divergent lens
(c) a rectangular slab
(d) a prism.

Q. 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.
