It is important to point out that we are not so much interested in dispersive prisms that split a beam of white light into its spectrum of colors, although they make great album covers.

White light is made of a spectrum of different colours. Light can be split up into these separate colours using a prism. There are three primary colours of light, which can be combined to make ...

IT is reported from Italy that three optical prisms formerly belonging to Sir ... and subsequent work of Newton on the dispersion of white light. Signor Algarotti was a great admirer of Newton ...

We can separate white light into all its different colours using a glass prism. The prism bends different colours of light at different angles. This is called refraction. This can happen in ...

Newton was also the first to understand the rainbow, and to refract white light with a prism into its component colours and back again into white light, establishing rigid experimental proof in ...
