WebA higher optical density indicates how much slower the wave travels through that material. When light refracts from one medium to another, one is said to be rarer, while the other is said to be denser. As a result, the term "rarer and denser medium" is a relative one. WebEarth’s atmosphere consists of different layers of air, where some are cold, and others are comparatively hot. The cool air in the atmosphere acts as an optically denser medium for light rays, while hotter air acts as an optically rarer medium; this is because hot air is lighter than the cold air.

Refraction and light bending (article) Khan Academy

WebApr 12, 2024 · When a light ray travels from one optical medium to another optical medium, it suffers a change of direction at the surface of separation of the two media. This is … Weba) The light travels from a rarer medium (air) to a denser medium (optical fibre). Hence the refracted ray will bend towards the normal. b) The angle of refraction can be calculated as follows: Let air be medium 1 and optical fibre be medium 2.
