Link to Course Overview
In this block will study towards the waves external exam: Doppler effect, standing waves, beats, interferences...
We'll investigate how instruments form standing waves see here: https://www.youtube.com/watch?v=ATom1MCwkTM :p to produce musical notes and why musical instruments sound different to each other even when playing the same note.
We'll look at how notes can add in and out of phase to vary the volume of the heard frequency producing beats.
We'll look at how relative velocity of the source and observer affects the frequency of the sound heard and explain that mathematically.

There should also be some time to work on revision for mechanics and work towards electricity if you wish to do all the externals.
At some point we'll have to use one week for derived grade assessments.
