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!
