Question

A 1.8-m-tall diver is standing completely submerged on the bottom of a swimming pool, in 3.0 m of water. You are sitting on the end of the diving board, almost directly over her.
Required:
How tall does the diver appear to be?

Answer 1

Answer:

$H=1.35m$

Explanation:

From the question we are told that:

Height $h=1.8m$

Depth of Water $d=3.0m$

Where

Refraction index of water $n = 4 / 3$

Generally the equation for Apparent height of the diver  is mathematically given by

$H=h\frac{h}{n}$

$H=\frac{1.8}{\frac{4}{3}}$

$H=1.35m$
