Chapter 10 - Superposition
In the GCE A Levels, we need to be able to explain the principle of superposition. This video will explain what this is, and also introduce the term coherence. We will see that when coherent waves superpose with one another, we will get a unique effect known as interference.
When studying the interference of two coherent waves at a point, we have to determine the phase difference between the waves at that point. For the GCE A Levels, the three main factors to consider will be the inherent phase difference of the sources, the number of reflections taken by the waves, and also the path difference of the waves. This video will explain how to put these factors together.
