How Rainbows Form

The video explores why the sky is darker above a rainbow, using concepts like refraction, dispersion, and reflection of light. It explains how light bends when moving between air and water, causing a spectrum of colors. The video details how rainbows form, why red light appears higher than violet, and why the sky is lighter below a rainbow. It also covers the phenomenon of double rainbows, where light reflects twice inside water droplets, flipping the color order. The explanation includes why certain colors appear brighter and how maximum angles affect color visibility.

What is the significance of the maximum angle of light exiting a water droplet?

Describe the process that leads to the appearance of a second rainbow.
