Why do rainbows form?

 Q:   Ask a Question about Why do rainbows form?       
Why do rainbows form? Rainbows are formed when sunlight falling on raindrops is split into the different colors of the spectrum (range) of light. Sunlight is really a mixture of all the colors of the spectrum: red, orange, yellow, green, blue, indigo and violet, but our eyes always see them as ordinary white light.

When a beam of light passes at an angle through a curved transparent surface, such as a raindrop, the beam is bent when it emerges. The different colors of light are bent by different amounts, so the white light is split into the colors of the spectrum. This effect can also be seen when light passes through a piece of glass cut at different angles, such as a prism.

Although it might seem that gravity carries food and drink down our throats, astronauts are able to eat and drink perfectly well in zero gravity. This is because it is muscular contractions of the gullet that actually transport food and drink to the stomach.

As light is split by water droplets into a rainbow, colors always produced in the same sequence: red, orange, yellow, green, blue, indigo and violet. Ultraviolet and infrared are a produced, but are not visible to the human eye.
