1.1 periodieke verschijnselen

Proefje:
Bij dezelfde touwlengte is de tijd v/e volledige heen en weer gaande beweging
onafhankelijk v/d slingerende massa. (de tijd blijft dus hetzelfde als het dezelfde
touwlengte heeft )



Periodieke beweging = een beweging die zich constant herhaalt

Cyclus = een deel v/d beweging die zich steeds herhaalt

Periode = T , is de vaste tijdsduur van één cyclus  wordt uitgedrukt in seconde (klok = 60s)

Frequentie = f , het aantal cycli per seconde  wordt uitgedrukt in Hertz (Hz)
