The theory of simple harmonic motion can be expanded upon by adding more oscillators to the system, leading to coupled oscillations.

This physics may appear unnecessary, at most causing some waves to be higher than others at sea. But this theory has been essential in so many fields. It is for example just this theory that described the bizarre physics of the double-slit experiment, one of the most famous experiments ever that laid the foundations for the theory of quantum mechanics.

In this unit we will discuss coupled oscillations, alongside some other relevant concepts.
