RAINBOWS
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 a particular angle.
When white sunlight enters a raindrop, it exits the raindrop 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. Together, these colours are known as
the spectrum. These colours can sometimes be seen in waterfalls and fountains as well.
Did you know that there are double rainbows also? In a double rainbow, light reflects twice
inside water droplets and forms two arcs. In most double rainbows, the colours of the
top arc are opposite from those in the bottom arc. In other words, the order of colours
starts with purple on top and ends with the red on bottom. Rainbows sometimes appear
as white arcs at night. These rainbows are called moonbows. Moonbows are caused by
moonlight shining through drops of water.
