¿Qué es un arcoíris?

The video explains how rainbows form, requiring the sun to be low in the sky and water in the air. It describes the process of light refraction, where light slows down and changes direction when passing through water droplets, separating into different colors. This separation and reflection of light create the rainbow's arc shape. The video also discusses how different colors refract at different angles, contributing to the rainbow's appearance, and why rainbows seem to move away as you approach them.

What happens to light when it passes from air into a droplet of water?

Why can you never get close to a rainbow?
