Question

a convex lens of refractive index 1.45,is dipped into a liquid of refractive index 1.45 shown in figure given below it will behave as
Divergent/convergent/invisible/glass slab

Answer 1

Glass slab is the right answer

Answer 2

Answer:

It will behave as invisible and there will be no effect.

Explanation:

• There won't be any refraction since there won't be any change in the speed of light at any point when the lens' optical density is equal to that of the medium.
• Therefore, the light is neither diverged nor converged.
• If the liquid is a Rarer surrounding medium then the convex lens will behave as Converging lens and Concave lens as Diverging Lens.
• If the liquid is a Denser surrounding medium then the convex lens will behave as Diverging lens and Concave lens as Converging Lens.

So we conclude that as the refractive index of lens and and liquid is same, in that case there will be converging and diverging or Ray light. It will act as invisible.
