Refraction of light through a glass prism Refraction is the bending of light when it goes from one medium to another so, ... The rainbow. Rainbow is formed ... it is called Tyndall effect.

Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light ...

The incident lightwave, being powerful enough, creates nonlinear effects inside the glass fiber, generating new light waves with longer and shorter wavelengths (visible and multi-colored).

In a glass or acrylic prism, the speed of light is approximately 66% of what it is in vacuum, which is why shining sunbeams through them separates them into colors so easily.

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.

The refraction of light at an interface is familiar as a rainbow or the 'bending' of a pencil in a glass of water. Here we show that particles can also be refracted and even totally internally ...
