Answer 2

Explanation:

Given:A fish at the bottom of a pond appears to be 1.2 m from the water surface.

To find:What is the depth of the pond?

Solution:

We know that

$D_{apparent}=\frac{D_{actual}}{μ}$

The refracting index of water is 1.33

Since,

Apparent depth is given,it is 1.2 m

Place these values in the formula above

$1.2 = \frac{D_{actual}}{1.33} \\ \\ D_{actual} = 1.2 \times 1.33 \\ \\ D_{actual} = 1.596 \: m$

Thus,

Actual depth of tank is ≈ 1.59 m

Final answer:

Option D is correct.

Hope it helps you.
