Question

A thin lens is made with a material having refractive index
\[\mu = 1 \cdot 5\]. Both the side are convex. It is dipped in water \[\mu = 1 \cdot 33\]. It will behave like

पर्याय

• A convergent lens

• A divergent lens

•  A rectangular slab

• A prism.

Answer 1

A convergent lens
Explanation:
Since the refractive index of the lens is more than that of water and both sides are convex, it will act like a normal convergent lens though its focal length will change.
