How is a rainbow formed?
<|assistant|>
A rainbow is formed when the sun is shining and the raindrops act like tiny little prisms refracting the light from the sun onto the Earth’s surface, creating the multicolored arc seen in a rainbow. The colors are actually all at the same angle with respect to the surface of the Earth as the rain drops travel in a circular path before the falling rain reaches the ground.
