A convex lens of crown glass (n =1.525) will behave as a divergent lens if immersed in

A

water `(mu=1.33)`

B

a medium of `(mu=1.525)`

C

carbon disulphide `(mu=1.66)`

D

it cannot act as a divergent lens

Text Solution

Verified by Experts

The correct Answer is:
C
Nature of a lens is reversed if it is immersed in a denser medium (of refractive index higher than that of the lens).
`(mu=1.525).` Hence, crown glass lens should be dipped in carbon disulphide.

A convex lens of glass (mu_(g)=1.45) has focal length f_(g) is air. The lens is immersed in a liquid of refractive index (mu_(g)) 1.3. The ratio of the f_(liquid)//f_(g) is

Assertion:A convex lens and a concave lens are kept in contact. They will behave as a diverging lens if focal length of convex lens is more. Reason: Power of a concave lens is always less than the power of a convex lens, as power of concave lens is negative whereas power of convex lens is positive.
