Question

A fish lies at the buttom of $4m$ deep water lake.A bird files $6m$ above the water surface. Then distance between the $(\mu$ of water $=1/3)$

• A. Bird and image of fish is $9m$
• B. Fish and image of bird is $12m$
• C. Fish and image of bird is $8m$
• D. Fish and image of bird is $10m$

Answer 1

The correct option is A Bird and image of fish is $9m$

Given ${\mu }_{water}=4/3$
For Fish
Apparent depth= Real death$\times \left(\frac{4}{3}\right)$
$=4\times \frac{3}{4}=3m$
Distance between bird is not equal to Image of fish
=$6+3=9m$
