Grundlæggende inden for Harmoniske bølger. Del 1.

Transversale bølger. Svingninger der går imod bevægelsesretningen.
Longitudinale bølger. Svingninger der er parallelle med bevægelssretningen.
Ampitude. A Er det tegn der bruges om en bølges højde og det måles i meter. Altså det maksimale udsving for bølgen.
Lampda. λ Er det tegn der bruges om længden fra en bølgetop til en anden, måles i meter.
Periode. T Den tid det tager 2 bølgetoppe at passere et givent punkt, måles i s.
Frekvens. f Hvor mange bølgetoppe der passere på et sekund. Måles i Hz.
Formlen for frekvens. f=1/T
Bølgehastighed. v Udbrædelseshastigheden for en bølgetop. Måles i meter i sekundet.
Formel for udbrædelseshastigheden. v=λ/T eller v=λ*f
