Description

Overview of the essential ideas for this topic

4.1: A study of oscillations underpins many areas of physics with simple harmonic motion (shm), a fundamental oscillation that appears in various natural phenomena.

4.2: There are many forms of waves available to be studied. A common characteristic of all travelling waves is that they carry energy, but generally the medium through which they travel will not be permanently disturbed.

4.3: All waves can be described by the same sets of mathematical ideas. Detailed knowledge of one area leads to the possibility of prediction in another.

4.4: Waves interact with media and each other in a number of ways that can be unexpected and useful.

4.5: When travelling waves meet they can superpose to form standing waves in which energy may not be transferred.
