A lens behaves as a diverging lens in air and converging lens in water.The refractive index of the material of the lens is __________ .

A

greater than refractive index of water

B

equal to refractive index of water

C

between 1 and refractive index of water

D

equal to unity

Text Solution

Verified by Experts

The correct Answer is:
C
When the light ray travels from air to lens, then it acts as a diverging lens . The same lens can act as a converging lens if light enters the lens from a denser medium. As such, the refractive index of the material of less the refractive index of water.
