__//Why do we see rainbows?//__ We see rainbows after if rain because the sun light passes through the raindrops and the light passes through different substances at different speeds. The light passes through the water and it slows the light down. When the light slows down it causes the light to bend or refract.



A double rainbows is when the light passes through the water drops twice .The colors of the second rainbow are reversed so violet is on top and red is on the bottom.

Did you know that a rainbow is actually a full circle? Did you know when a rainbow appears, the sun will always be behind you and the rain will always be in front of you? Did you know a rainbow will always be facing directly opposite the sun?
