This precise optical glass prism produces beautifully clear spectrums with very bright colours of the rainbow. Put it on a window ledge in the direct sun.
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. Sir Isaac Newton in the 17th century was the first to prove that white light was in fact made up of different colours. He used a glass prism in his experiments. The corners of the prism are ground for safety.
50mm long. Each face 28mm.
