Lesson Plan: Interactions of Electromagnetic Waves with Matter Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the effects of different types of electromagnetic waves on matter, including their effects on the human body.
Objectives
Students will be able to
- distinguish between electromagnetic waves from different parts of the electromagnetic spectrum in terms of their propensity to produce ionization in matter,
- distinguish between electromagnetic waves from different parts of the electromagnetic spectrum in terms of which substances they are strongly absorbed by and which substances they are weakly absorbed by,
- distinguish between electromagnetic waves from different parts of the electromagnetic spectrum in terms of which substances they are strongly reflected by and which substances they are weakly reflected by,
- distinguish between electromagnetic waves from different parts of the electromagnetic spectrum in terms of the health hazard they present to living organisms.
Prerequisites
Students should already be familiar with
- the wavelength ranges of different types of electromagnetic waves within the electromagnetic spectrum.
Exclusions
Students will not cover
- any calculations related to electromagnetic waves.
