Optics Question 759

Question: Each quarter of a vessel of depth H is filled with liquids of the refractive indices n1,n2,n3and n4 from the bottom respectively. The apparent depth of the vessel when looked normally is

[AMU (Engg.) 2000]

Options:

A) H(n1+n2+n3+n4)4

B) H(1n1+1n2+1n3+1n4)4

C) (n1+n2+n3+n4)4H

D) H(1n1+1n2+1n3+1n4)2

Show Answer

Answer:

Correct Answer: B

Solution:

Apparent depth of bottom = H/4μ1+H/4μ2+H/4μ3+H/4μ4

=H4(1μ1+1μ2+1μ3+1μ4)
