Question on: JAMB Physics - 2024
Calculate the depth of a swimming pool if the apparent depth is 10 cm. (Refractive index of water = 1.33)
A
7.5 cm
B
10.0 cm
C
13.3 cm
D
6.87 cm
Ask EduPadi AI for a detailed answer
Correct Option: C
The relationship between real depth and apparent depth is given by the refractive index formula:
Refractive index (n) = Real depth / Apparent depth
Given:
- Apparent depth = 10 cm
- Refractive index of water (n) = 1.33
Real depth = Refractive index x Apparent depth = 1.33 x 10 cm = 13.3 cm
