A thin convex lens made of glass of refractive index 3//2 has a power of 5 D. When it is immersed in a liquid of refractive index mu , it behaves like a divergent lens of focal length 1 m. Calculate the refractive index of the liquid.

A convex lens made of a glass of refractive index 3//2 has a focal length 'f' in air. If it is immersed into water of refractive index 4//3 , then with calculation, predict the new focal length of the lens inside water.

A convex lens of refractive index n behaves as a convex lens of smaller power in a liquid of refractive index n_1 and as a concave lens in another liquid of refractive index n_2 . Then relation between n, n_1 and n_2 is
