Refraction in the Atmosphere

The video tutorial explains the concept of refraction, highlighting how light bends when passing through different media. It discusses atmospheric refraction, which allows the sun to be visible even after it sets. The tutorial also covers mirages, optical illusions caused by light bending in hot air, and explains how rainbows form through reflection and refraction in water droplets, resulting in a spectrum of colors.
