Lesson Plan: Reflection of Light
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define reflection, describe the link between the angles of incoming and reflected light rays, explain how we see objects, and identify uses of mirrors.
Objectives
Students will be able to
- define reflection,
- identify surfaces that cause regular reflection,
- describe the link between the angle of an incoming light ray and the angle of the reflected light ray during regular reflection from smooth surfaces,
- explain how we see objects that give out and reflect light,
- describe how our eyes respond to variations in the amount of light,
- describe ways in which we use mirrors, including in periscopes.
Prerequisites
Students should already be familiar with
- the fact that light travels in straight lines,
- the fact that the Sun is luminous but the Moon is not.
Exclusions
Students will not cover
- the terms angle of incidence and angle of reflection,
- the normal line,
- the term law of reflection.
