Question

suppose a swimming pool is filled with an imaginary liquid which is optically rarer than air. For a person looking at the pool from outside, will the apparent depth of the pool be less than or greater than the real depth? Give reasons.

Answer 1

The apparent depth of the pool in this case is greater than the real depth of the swimming pool as seen by the person.

• The refraction phenomena of light occur when light from any object passes through a medium that is rarer and denser.
• Drawing an imaginary line called normal can help you understand how light refracts.
• Due to its increased speed, light in a rarer medium bends away from the standard line.
• When light travels through a denser medium, it bends towards the normal line as its speed decreases.
• The liquid in the swimming pool is a rarer medium than the air outside in this situation.
• When viewed from the outside, the swimming pool appears to be deeper than it actually is.
• Because the light from the pool's surface bends or refracts towards the normal when it passes through a denser medium.
• As a result, the apparent depth will be greater, in this case.
