A double convex air bubble in water behaves as
- A convergent lens
- B divergent lens
- C plane slab
- D concave mirror
Answer & Solution
Correct Answer
(B) divergent lens
Step-by-step Solution
Detailed explanation
\(\mu_{\text {water }}=1.33 \text { and } \mu_{\text {air }}=1\)
As air is optically rarer, \(\mu_{\text {air }} < \mu_{\text {glass, }}\), converging nature of the convex lens changes to diverging.
Thus it behaves as divergent lens.
As air is optically rarer, \(\mu_{\text {air }} < \mu_{\text {glass, }}\), converging nature of the convex lens changes to diverging.
Thus it behaves as divergent lens.
