¿Qué es un arco iris?

The video explains how rainbows form, requiring sunlight at a low angle and water droplets. Light slows and refracts in water, separating into colors due to different wavelengths. This separation creates the rainbow arc, visible at specific angles. The illusion of a rainbow persists as new droplets recreate it, making it impossible to reach.

Why does a rainbow appear as an arc?

What is the significance of the angle at which colors are refracted in a raindrop?
