Question

We have an aquarium which is divided into two halves each having a fish.The first half is filled with a liquid of refractive index 6/5.the other half of refractive index 4/3.The two halves are joined together by a curved surface of refractive index 3/2 and radius of curvature 30cm.Both the fishes are at a distance of 6cm from the curved surface.
Find the apparent position of fish in the part having refractive index (4/3) as seen by other fish.

Answer 1

I m getting ans as 11.29 cm.

Answer 2

The thin curved glass sheet has two surfaces.(pls don't consider a single surface for that).

Answer 3

Use the formula of refraction at spherical surface twice..

Answer 4

I did that only and got this ans 11.29 .
Bt the ans is diff.
The ans they hve given is 5.29 which i got for an observer in the part having refractive index 6/5 (very close to the curved surface) and not for the fish which is 6cm away from the curved sheet.

Answer 5

The curve surface is concave or convex ...

Answer 6

Concave to the observer and convex to the object.

Answer 7

When i say observer it is nothing but the fish in part of refractive index 4/3.
And similarly u can judge for the other half.

Answer 8

I hate calculation
