U4AOS1 Topic 6: Waves

$f = \frac{1}{time}$Longitudinal waves are where the wave oscillations are parallel to the direction of the wave travel (air, inside fluids, etc).

Transversal waves are where the wave oscillations are perpendicular to the direction of the wave travel (solids, surface of fluids, etc).

   The simulation below shows how a particle moves on each type of wave

The frequency of a wave can be calculated through the formula

$f = \frac{1}{T}$

$f = \frac{1}{time}$
​1/time

Where f is measured in Hertz (Hz) and T is the time for one period in seconds (s).

There are two graphs for waves.

1. Distance vs Displacement

This graph tells us the amplitude and wavelength.

2. Distance vs Time

This graph tells us the amplitude, period and frequency.
