Apparent depth d is given by ⇒ d=(t1/μ 1)+(t2/μ 2) ⇒ d=(4/1.4)+(5/1.5)=2.857+3.333 ⇒ d=6.190cm

Q. The apparent depth of an object $O$ from $A B$ is

$4.29 c m$

$5.43 c m$

$6.19 c m$

$5.99 c m$

Apparent depth $d$ is given by
$\Rightarrow d = \frac{t _{1}}{μ _{1}} + \frac{t _{2}}{μ _{2}}$
$\Rightarrow d = \frac{4}{1.4} + \frac{5}{1.5} = 2.857 + 3.333$
$\Rightarrow d = 6.190 c m$
