UNIT 1
MODULE 2: OSCILLATIONS AND WAVES

GENERAL OBJECTIVES

On completion of this Module, students should:

1. understand the different types of oscillatory motion;

2. appreciate the properties common to all waves;

3. recognise the unique properties of different types of waves; and,

4. apply their knowledge of waves to the functioning of the eye and the ear.
