Buy optical prisms & make rainbows colour your walls & your life. Make beautiful rainbow spectra with our prisms and diffraction grating.
This prism is made using optical glass and will demonstrate that white light is made up of the colours of the rainbow. This is known as a spectrum. In the 17th century Sir Isaac Newton was the first to prove that white light was in fact made up of different colours. This prism is very good for producing rainbows from sunlight, but if you want more control, try our Rainbow Spectrum kit.
Rainbow Spectrum Kit This kit - produced by Curious Minds - enables you to create spectra in the absence of bright sunlight, using a glass lens together with a prism or diffraction grating, and a white light. The instruction booklet contains several experiments, and explains enough science to understand the results. Newton would have been delighted!
