A:
- Rainbows are created due to reflection, refraction, and dispersion of light in water droplets. It forms a spectrum of light as a circular arc in the sky.
- When light enters a water droplet due to refraction the light is split into different colors which then get reflected out of it.
- The rainbow forms a circle but only the arc is visible from the ground.
