Question

A convexo-convex lens of refractive index $1.47$ is dipped in a liquid, then it behaves like a simple plane sheet of glass. It means, the refractive index of liquid is:

• A. Greater than the refractive index of glass
• B. Less than the refractive index of glass
• C. Equal to the refractive index of glass
• D. Less than one

Answer 1

Answer: (C)

Equal to the refractive index of glass

The refractive index of liquid is equal to the refractive index of glass
