Question

Calculation of to find the refractive indices of water and oil by using plane mirror an

Answer 1

Answer:

Let's add small amount of water on a flat, plane surface and place a convex lens over it.

This forms a plano-concave lens of water between the lower surface of convex lens and plane mirror.

R 1 = R and R 2 = for water lens. (where 'R' is the radius of curvature of the concave surfaces of the plano-concave lens).

Answer 2

Hiiii dude......

The radius of the lower surface of the convex lens is given by: R = l 2 6h + h 2 Here, l is the average distance between the legs of the spherometer and h is the difference in the reading of the spherometer when placed first on the convex lens and then on plane mirror.
