When a biconvex lens of glass having refractive index `1.47` is dipped in a liquid, it acts as a plane sheet of glass. This implies that the liquid must have refractive index.

What happens when a convex lens of refractive index 1.2 is immersed in a liquid of refractive index 1.3?

A bi-convex lens made of glass (refractive index 1.5) is put in a liquid of refractive index 1.7. Its focal length will

A thin equi-convex lens is made of glass of refractive index 1.5 and its length is 0.2 m. If it acts as a concave lens of 0.5 m focal length when dipped in a liquid, the refractive index of the liquid is

A thin equi-convex lens is made of glass of refractive index 1.5 and its length is 0.2 m. If it acts as a concave lens of 0.5 m focal length when dipped in a liquid, the refractive index of the liquid is

A glass lens of refractive index 1.45 disappears when immersed in a liquid. What is the value of refractive index of the liquid ?
