Question

A convex lens of crown glass (n=1.525) will behave as a divergent lens if
immersed in
Water (n =1.33)
In a medium of n = 1.525
Carbon disulphide n =1.66
It cannot act as a divergent lens​

Answer 1

Answer:

Explanation:

Refractive index deals with the speed of light.

Light will travel faster in a medium with low n value.

so option (D) is correct

Answer 2

Answer:

option (c)

carbon disulphide n-1.66
