WebApr 7, 2024 · Total internal reflection happens at a time when a light ray that travels from a denser to a rarer medium. The ray is incident at an angle of incidence that is greater than the critical angle. After that, the light rays are reflected in another denser medium. It is the same medium before reflection. WebApr 6, 2024 · In which direction will light bend when travelling from an optically rarer medium to an optically denser medium? Answer: The bending of light as it passes from one transparent medium to another is called refraction. It occurs because light travels at lower speed in an optically denser medium.

Webi understood that light takes a short path (refracts) as it goes from rarer to denser due to more density (more obstruction from particles of medium). but who is giving it energy to move with the same speed after second refraction (from denser to rarer). • ( 18 votes) Upvote Flag Francesco Maoli 8 years ago 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.
