The Reason for a Swimming Pool to appear Less Deep than the actual depth is

A. Refraction
B. Light scattering
C. Reflection
D. Interference

Check Answer

The correct answer is option A. Refraction.

The reason for a swimming pool to appear less deep than the actual depth is refraction. When light passes through a medium of different density, its speed changes, and it bends or refracts. The surface of the water in a swimming pool acts as a boundary between two mediums: air and water, and the light passing through it bends as it enters the water. This bending of light makes the bottom of the pool appear higher than it actually is, causing the pool to appear shallower than its actual depth.
