Calculate the depth of a swimming pool if the apparent depth is 10cm. ( Refractive index of water = 1.33 )
Refractive index = \(\frac{\text{real depth}}{\text{apparent depth}}\)
Real depth = refractive index x apparent depth
Apparent depth = 10cm
Refractive index = 1.33
Real depth = 1.33 x 10 = 13.3cm.
There is an explanation video available below.
