A convex lens made up of glass of refractive index `1.5` is dippedin turn
(i) in a medium of refractive index `1.65`
(ii) in a medium of refractive index `1.33`
Then Will it behave as converging or diverging lens in the two cases ?

Explanation

To determine whether a convex lens behaves as a converging or diverging lens when dipped in different media, we can use the Lens Maker's formula. The formula is given by:

\[ f = \frac{R}{\mu - 1} \]

where:
- \( f \) is the focal length of the lens,
- \( R \) is the effective radius of curvature of the lens,
- \( \mu \) is the refractive index of the lens material relative to the medium.
