Question

A rectangular tank of depth 8 meter is full of water (u=4\3), the bottom is seen at the depth X meter ..find the value of x

Answer 1

Here you should use the formula,
refractive index of water with respect to air = actual depth/virtual depth.

Given, refractive index of water = 4/3
actual depth = 8m
Virtual depth = X m
∴ 4/3 = 8 /X
⇒X = 8 × 3/4 = 6 m

Hence, answer is X = 6 m

Answer 2

Hello Dear.

Here is the answer---

Given Conditions,
Depth of the Tank = 8 m.
Refractive Index(μ) = 4/3
Apparent Depth = X m.

Using the Formula,

 μ = Real Depth/Apparent Depth
4/3 = 8/x
x = (8 × 3)/4
x = 6 m .

Thus, the Depth to which the water will be seen is 6 m.


Hope it helps.
