This module discusses the nature and properties of light. It delves into the concepts of reflection, refraction, colors, interference, and polarization.
Objective
1. state the different theories about the nature of light.
2. demonstrate reflection properties of light using mirrors.
3. describe the image formed by mirrors.
4. show the refraction properties of light using lenses.
5. give applications of total internal reflection.
6. describe the image formed by lenses.
7. enumerate the colors that make up white light.
8. explain what causes colors of object.
9. cite applications of diffractions, interference and polarization of light.
