Under this topic, we will be discussing about the following...
Light - Lenses
Discussion of some of the main features of thin converging lenses with a labeled ray diagram. A series of important ray diagrams and its application will also be discussed.
Light - Refraction
State and discuss the 2 laws of refraction, refractive index and some common phenomena of refraction in our daily life.
Light - Reflection
State and discuss the 2 laws of reflection, types of reflection, ray diagrams for plane mirror and some common applications of reflection.
