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.

What is refraction and how does it occur in different mediums?

Explain how atmospheric refraction affects the visibility of the sun after it has set.

Describe the phenomenon of a mirage and the conditions under which it occurs.

What causes the formation of rainbows, and how do reflection and refraction contribute to this phenomenon?

How does the wavelength of light affect its refraction in water droplets?
