WEEK+5_Acoustics

> **Speed** is the distance travelled in unit time (m/s) **Frequency** is the number of complete cycles in one second (Hz  **Wavelength** distance between matching points on the wave (m)  This is sometimes called Lambda (λ) and it is measured in metres (m).
 *  SOUND AND ACOUSTICS
 * **Longitudinal** vibration parallel to direction of travel of wave

> **Transverse** vibration at right angle to direction of travel of wave > > > > > > The Wave Equation is: Speed (v) = Frequency (f) x Wavelength (λ)
 * f = v / λ λ = v / f [[image:Imagen3.png width="236" height="182"]][[image:Imagen1.png width="214" height="157"]][[image:Imagen4.png width="182" height="143"]][[image:anabelfreitasid2126dg12/Imagen2.png width="296" height="156"]]
