1.	A lens behaves as a converging lens in air and a diverging lens in water (u = 4/3). What will be the condition on the value of refractive index (u) of the material of the lens?
Answer» A lens behaves as a converging lens in air and a diverging lens in water (u = 4/3). It means REFRACTIVE index of the MATERIAL of lens is less than the refractive index of water. The CONDITION is that the refractive index of a material of a lens is less than the refractive index of water.Explanation:Pls mark me as BRAINLIEST
