Calculate the depth of a swimming pool if the apparent depth is 10cm. ( Refractive index of water = 1.33 )
A
7.5cm
B
10.0cm
C
13.3cm
D
6.87cm
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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.
