Ask.com Answer for: why are rainbows curved
Rainbows form when sunlight is refracted into separate colors by water droplets. We usually see rainbows as arcs due to each individual color refracting at different angles.
Though a rainbow spans a continuous spectrum of colors, the human eye usually perceives bands of seven distinct colors: red, orange, yellow, green, blue, indigo and violet.
Rainbows are curved because all of the angles in the water drop have to be just right in order to send some sunlight to you while you are standing on the ground. The rainbow is curved because the set of all the raindrops that have the right angle between you, the sun, and the drop lie on a cone pointing at the sun with you at one tip.
