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.

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 ...

We can split white light into a spectrum of colours using glass prisms or the reflective side of a CD. Most objects we think of as black aren't truly black. They are more usually very dark colours ...

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 ...
