In this block will study towards the waves external exam: Doppler effect, standing waves, beats, interferences... In the middle of this term we have the practice exam week.
We'll investigate how instruments form standing waves 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.
