Question

A vessel of depth 'd'is half filled with a liquid of refractive index py and the other half is filled with a liquid of refractive index ji2. The apparent depth of
the vessel, when looked at normally, is
(A) d(ui + M2)
(B) d (1+
H2
(C) (un + m2)
(D) (+)​

Answer 1

Correct option is

B

d(

Apparent depth =

refractive index

real depth

⇒ depth seen =

μ
