Calculate the depth of a swimming pool if the apparent depth is 10cm(refractive index of water is 1.33)
The apparent depth of an object in water (as viewed from air) is less than the real depth due to refraction. The relationship is given by:
\(\mu = \frac{\text{Real depth}}{\text{Apparent depth}}\)
where \(\mu\) is the refractive index of water (\(\mu = 1.33\)).
Rearranging for real depth: \(\text{Real depth} = \mu \times \text{Apparent depth} = 1.33 \times 10 \, \text{cm} = 13.3 \, \text{cm}\)
