What is denser medium and rarer medium?

Answer # 1 #

Imagine a crowded room (denser medium) versus an empty hall (rarer medium). Moving across the crowded room is slower because of obstacles, just like how waves slow down in denser media.

When light passes from a denser to a rarer medium, it bends away from the normal due to the change in speed. Water is denser than air, so a straw in a glass looks bent at the surface.

A denser medium has particles packed closely together, which slows down light or sound traveling through it. A rarer medium has fewer particles per unit volume, allowing faster wave propagation.
