Why is a rainbow curved?
Rainbows are sunlight reflected inside raindrops. They reflect at a fixed angle due to the way water bends light, but they can be in any orientation. All the sunlight is coming from the same direction (the sun).
The Short Answer
Rainbows are sunlight reflected inside raindrops. They reflect at a fixed angle due to the way water bends light, but they can be in any orientation. All the sunlight is coming from the same direction (the sun). If you take light from one direction change its path by a fixed angle in all directions, you end up with a circle.
