Answer :

Final answer:

The answer explains the role of refractive index in light behavior transition between air and water.


Explanation:

Refractive index plays a crucial role in determining how light behaves in different mediums like air and water.

When light travels from air to water, it bends due to the change in speed caused by the different refractive indices of air and water.

Understanding refraction can help in calculating distances and angles of light in scenarios like pool lighting.
