Glass Prism Refraction? Beautiful!
Rainbow light - everyday!
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.
