Use a prism like Newton did.

Simple. When white light is shined through a prism, the many surfaces bend the light so that the spectrum (rainbow) is formed. The spectrums' colors can be divided no further. This would mean that the colored light that we see when white light passes through a prism is, indeed, the white light itself.

^_-

They also make these neato little tubes that you can look at white light and see it as colored light. The colors depend on the exact wavelength of the color itself, and how much the color is refracted as it goes through the prism.

The colors are, in order, Red Orange Yellow Green Blue Indigo Violet

ROYGBIV.

My first reaction is which you would be able to injury illuminate into different wavelengths by employing employing a prism. yet then i presumed, how are you able to show that the prism merely did no longer create a gaggle of colours from the colour "white?" try this simple test. seem around once you notice issues with white gentle. Do you notice colours? That proves that white includes a mixture of colours (except you're shade blind). you notice, in case you had purely a organic crimson gentle the only shade you ought to work out could be crimson. crimson issues could seem crimson, yet green issues could seem black. that's as a results of fact what green gadgets do is soak up each and every of the colors different than green, that's scattered faraway from the fairway merchandise. whilst there is no green interior the sunshine which shines on a green merchandise, there is no longer something to scatter lower back into your eye. So all of it gets absorbed, and it seems black to you. A be attentive to warning in case you attempt to determine this out. Many colored lighting fixtures furniture are no longer in basic terms one shade, and a lot of gadgets are no longer organic colours the two. yet once you have extremely organic colours you will see the effect.

If you set up a prism and pass the white light through it different colors of light will be seen passing through the other side of the prism. See the album cover for one of Pink Floyd's records and you will see what I mean.
