Question

There are different fish, monkeys and
water of the habitable planet of the star
Proxima b. A fish swimming underwater
feels that there is a monkey at 2.5 m on the
top of a tree. The same monkey feels that
the fish is 1.6 m below the water surface.
Interestingly, height of the tree and the
depth at which the fish is swimming are
exactly same. Refractive index of that
water must be
(A) 6/5
(B) 5/4
(C) 4/3
(D) 715​

Answer 1

refractive index of that water must be 4/3
