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
Options
A convergent lens
A divergent lens
A rectangular slab
A prism.
Solution
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.

To a distant observer, the light appears to be coming from somewhere below the ground. The observer naturally assumes that light is being reflected from the ground, say, by a pool of water near the tall object. Such inverted images of distant tall objects cause an optical illusion to the observer. This phenomenon is called mirage. This type of mirage is especially common in hot deserts. Based on the above facts, answer the following question: |
