Sub-index for this section on visible light experiments

This page will answer many questions e.g.

How do draw ray diagrams for visible light ray refraction experiments?

How do we explain refraction by light waves?  How do you explain diffraction of light waves?

Why and how does a triangular prism produce a 'rainbow of colours'?

How do you construct ray diagrams from prism experiments?

1. Investigating refraction: air-prism or air-water interface, total internal reflection - fibre optics

2. The visible spectrum of light and triangular prism experiments to explain a 'rainbow'

3. Investigating diffraction of light e.g. effect of the surface of a CD (compact disc)

4. Examples of the coincidence of reflection and refraction at an interface
