Question

A rectangular tank of depth 8 meter is full of water (μ = 4 / 3 ), the bottom is seen at the depth(a) 6 m
(b) 8/3 m(c) 8 cm(d) 10 cm

Answer 1

Hey !!

Given Data,

Rectangular tank of depth = 8 m

Refractive index of the water = $\frac{4}{3}$

Apparent Depth = X m

= $\frac{4}{3}=\frac{8}{x}$

=>  X = ( 8 * 3 ) / 4

=> X = 6 m  

Option (A) 6 m

GOOD LUCK !!
