Rainbows are often seen when the sun comes out after or during a rainstorm. Rainbows are caused when sunlight shines through drops of water in the sky at specific angles. When white sunlight enters a raindrop, it exits the raindrop in a different colour. When light exits lots of different raindrops at different angles, it produces the red, orange, yellow, green, blue, indigo, and violet that you see in a rainbow. These colours can sometimes be seen in waterfalls and fountains as well. There are double rainbows in nature. In a double rainbow, light reflects twice inside water drops and forms two arcs. In most double rainbows, the colours o f the top arc are opposite to those in the bottom arc. In other words, the order of colours starts with violet on top and ends with red on bottom. In addition, rainbows sometimes appear as white arcs at night. These rainbows are called moonbows and are so rare that very few people will ever see one. Moonbows are caused by moonlight shining through drops of water.
