In this extract from the new book Beautiful Experiments: An Illustrated History of Experimental Science, science writer Philip Ball explains how Isaac Newton transformed our understanding of light.

Physicists tested the Greenberger–Horne–Zeilinger (GHZ) paradox, which is at the heart of quantum theory, to measure light ...

Light waves encountering a prism disperse to produce a rainbow of colors. Particles of light, or photons, strike electronic pixels inside digital cameras to create an image.

With this experiment, he proved for the first time that all the colors of the rainbow come from the light, and not directly from the prism. Isaac Newton did more experiments with light, and then ...

Twenty-odd years before Newton stated the three laws of motion, he conducted a simple, breakthrough prism experiment. He poked a hole through his window shade, allowing a single beam of light to ...

Learn about the spectrum of colours found in visible light, how to split white light and the primary and secondary colours of light in this guide for KS3 physics students aged 11-14 from BBC Bitesize.

What blue light is. If you remember your prism experiment from grade-school science, light is made up of several visible colors. One of these colors is blue light.

More than 350 years ago, a young Isaac Newton fundamentally altered our understanding of visible light when he put a glass prism to a beam of sunlight and saw an array of colors he already knew to ...

The title of this week’s episode of "Cosmos" is "Hiding in the Light," which — I must confess — evoked memories of a classic episode of "The X-Files," in which Mulder and Scully investigate ...
