The refraction of light in glass prism is different from a glass slab. This is because in glass prism, the incident ray of light is not parallel to emergent ray of light.

A prism constructed with this material demonstrates negative refraction of visible light, and is easily probed from free space, paving the way for practical optical device applications.

Save guides, add subjects and pick up where you left off with your BBC account. The incident ray is refracted towards the normal as it enters the glass prism from air. It is then refracted away ...

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.

In this way a prism can spread out a ray of white light into the rainbow spectrum. The spread of refractive colors can be observed in poor-quality binoculars and telescopes.

Refraction happens when light that is passing through one substance, like air, changes its speed when it enters another substance, like glass or water. Although it is commonly said that light ...
