Q. The reason for a swimming pool to appear less deep than the actual depth is? [UPPSC RO ARO 2024]
(a) Reflection
(b) Light scattering
(C) Refraction
(d) None of the above
Answer: c
This is because light rays from the bottom of the pool are bent away from the normal as they pass from water into the air. This phenomenon is called the refraction of light. Due to this the image of the bottom of the pool seems nearer to us and the pool appears less deep as shown in the figure.
