Incazelo yamagagasi adlulayo
Amagagasi ahambayo amagagasi lapho ukusabalala kwawo kuqonde ngqo ohlangothini lokudlidliza kwendawo adlula kuyo.

Izibonelo zamagagasi anqamulayo
Isibonelo segagasi eliphambeneyo igagasi elisentanjeni noma ocingweni. Uma igagasi elisentanjeni lihamba lisuka kwesobunxele liye kwesokudla, intambo iya phezulu naphansi, iqonde ngqo lapho kusabalala khona amagagasi.

Ijubane lokusabalala kwamagagasi linganqunywa kusetshenziswa ifomula ejwayelekile:
Incazelo yefomula:
v = isivinini sokusabalala kwamagagasi (amayunithi angamamitha/umzuzwana)
I-T = isikhathi segagasi = isikhathi esidingekayo ukuze igagasi lihambe ubude obulodwa begagasi (amayunithi angamasekhondi)
f = imvamisa = inani lamaza okukhanya adlula iphuzu elifanayo ngomzuzwana owodwa (iyunithi ingu-1 / umzuzwana = i-hertz)
i-lambda = ubude besikhathi (amayunithi angamamitha)
