Problem

A convex lens

L_1

and a concave lens

L_2

have refractive index 1.5. Match the following two columns.

Column I	Column II
(a) $L_1$ is immersed in a liquid of refractive index 1.4	(p) Lens will behave as convex lens
(b) $L_1$ is immersed in a liquid of refractive index 1.6	(q) Lens will behave as concave lens
(c) $L_2$ is immersed in a liquid of refractive index 1.4	(r) Magnitude of power of lens will increase
(d) $L_2$ is immersed in a liquid of refractive index 1.6	(s) Magnitude of power of lens will decrease
