Dispersion of light and colours: JAMB Physics Past Questions and Answers
What the JAMB syllabus covers in Dispersion of light and colours
Our summary: How a prism splits white light, how colours mix, and why objects have the colours they do.
- Dispersion of white light by a triangular prism
- Production of pure spectrum
- Colour mixing by addition and subtraction
- Colour of objects and colour filters
- Rainbow and formation
Objectives
- identify primary colours and obtain secondary colours by mixing;
- understand the formation of rainbow;
- deduce why objects have colours;
- analyse colours using colour filters;
- define monochromatic light.
