Why do rainbows form? How are they formed?
I'm curious about rainbows. Can you tell me why they form and how they're formed?
Sure! Rainbows form due to the refraction, dispersion, and reflection of light in water droplets. When sunlight shines through a droplet of water, it bends or refracts, then separates into the various colors of the visible spectrum due to the difference in the angle at which each color is refracted. This creates the characteristic arc of colors that we see in a rainbow.
