7 Colours of the Rainbow Have you ever seen a rainbow? Sometimes when the sun is shining and it is rainy somewhere at the same time, you can see a rainbow. It's a huge arch of colours in the sky. It's caused by the light from the sun being broken up by water droplets in the atmosphere. The sun's light is "white", but the water droplets break it up into seven different colours, always in this order: RED ORANGE YELLOW GREEN BLUE INDIGO VIOLET There is an easy way to remember them (a mnemonic): - Richard Of York Gave Battle In Vain These colours are the "visible" part of the sun's radiation. But do you know that there are many other parts that are not visible to the human eye??? For example: - immediately below red is "infraRED" - immediately beyond violet is "ultraVIOLET" (UV) |
