Chapter 9 - Waves
In the GCE A Levels, we are required to understand several different ways to classify waves, including mechanical waves, electromagnetic waves, progressive waves, stationary waves, transverse waves and longitudinal waves. This video will briefly describe these, and also look at the electromagnetic spectrum.
Waves can be represented using a displacement-time axis. This shows the motion of a single wave particle over time and it actually performs simple harmonic motion. The GCE A Levels requires us to recognise this representation and this video will discuss this.
