How are rainbows formed. I know it’s about refraction from water droplets, but shouldn’t you see many tiny rainbows instead of one big one.
In: Physics
For me, it’s helpful to remember that a rainbow is a circle. You usually just can’t see the other half. In the inner parts of a circle the spectrum continues. The ultra violet and higher frequencies keep going. Outside the circle, the infra red and lower frequencies continue. A rainbow only appears like it does to us because we can only see a small segment of the spectrum.
