A convex lens will behave as a concave lens when placed in 1) water 2) oil 3 both 4 none i know that it will do so when it will be placed in a medium having higher refractive index then i think answer should be 2 but it is given 3 is it correct if yes tell me how as refractive i of lens > water AFMC 2003 qns Rates assured

Yup.
Might be a printing mistake.
R U sure the answer shud be 2? What's the refractive index of oil? It is more than glass and water?

If the RI of the medium in which the lens is placed is more than the RI of the material of the lens, then the lens changes its behavior. A convex lens behaves as a concave lens and vice-versa.
ed ; it is a mistake in Q ( assumed RI of oil is greater than that of lens material )

it is not important where u stand, but in which direction u are moving |

Glass has r.i of 1.5. Oil has more I think. So, answer should be oil.
