The visible spectrum and colour

 Doc Brown's GCSE level physics notes

Sub-index for section on 'COLOUR'

1. Reminder: Dispersion of light by a prism showing visible spectrum

2. What is colour? selected technical data on visible spectrum colours

3. What do mean by opaque, transparent and translucent materials?

4. Primary and secondary colours explained

5. The eye and TV screens

6. Visible light filters, observed colour of objects subjected to various light colours

7. More on what determines the colour of an object you observe without the screening effect of filters and colours of solutions you come across in chemistry!
