IB Physics C2 Notes

In Topic C.1, you learned about simple harmonic motion. Remember that waves are one of the examples of oscillations that exhibit SHM. In this topic, you learned about a particular type of wave that does this, called a travelling wave. 

A travelling wave is defined as an oscillating wave that transfers energy through a medium via the movement of particles in the direction of the wave. These waves always have a constant speed (v) that is dependent on wave frequency (f) or period (T) and wavelength (λ)

$v = f\lambda = \frac{\lambda}{T}$

However, particles can move in two directions, forming either transverse waves or longitudinal waves. Let’s cover each one now.
