Question

1.Problem: A vessel is quarter filled with a liquid of refractive index A. the remaining parts of the vessel is filled with an immiscible liquid of refractive index 3A/2. The apparent depth of the vessel is 50% of the actual depth. the value of A is?
1)1 2)3/2 3)2/3 4)4/3

Solution: 1
But i dont have a clue how to solve this sum plzz help.

Answer 1

Refractive index=u/v

Answer 2

u=object distance
v=image distance

Answer 3

So
A=u/v

Answer 4

Try this equation for second lequid

Answer 5
