Dispersion Of White Light
-Sunlight appears to be white but it is actually composed of different colours.
1. When a beam of white light passes through a prism, it is split into different colours.
2. This is because the different colour of white light bend towards the normal through different angles when entering the prism and when leaving the prism too.
3. A spectrum of colours is produced, which is made up of seven colours: Red, Orange, Yellow, Green, Blue, Indigo, Violet. This splitting of white light is called dispersion.
