Transversale golf = beweegt op en neer, eendje blijft op dezelfde plek drijven
Longitudinale golf = beweegt naar links en rechts, samendrukking en uitrekking, golf verplaatst zich
over afstand

Harmonische golf = vibratie/trilling waarbij de uitwijking in functie van de tijd in een sinus-vormige
functie resulteert

U(t) = U0 sin wt
W = 2pi f

U = diversion at any time (m) uitwijking
T = trillingstijd/periodetijd (s) duur van 1 trilling
F = frequentie/aantal trillingen per seconde (Hz of s-1)
A0 = amplitude  de maximale uitwijking van de vibratie/trilling = U0
Labda = golflengte (m)

T = 1/f
f = 1/T
