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.
Izingxenye zamagagasi anqamulayo
Umcibisholo obomvu ngakwesokudla ubonisa indlela yokunyakaza kwamagagasi. Imicibisholo ebomvu phezulu naphansi ikhombisa indlela yokunyakaza kwengxenye ngayinye yentambo.
I-A (amplitude) = ukuphambuka okukhulu kwentambo
I-Lambda (ubude begagasi) = ibanga eliphakathi kweziqongo ezimbili ezilandelanayo = ibanga eliphakathi kwezingodo ezimbili ezilandelanayo = ibanga eliphakathi kwamaphuzu amabili alandelanayo obude obufanayo. Iphuzu liwukuthi ubude begagasi elilodwa bune-crest eyodwa kanye nomgodi owodwa.
a – b = igquma lamagagasi
b – c = isigodi samagagasi
Imvamisa (f) yegagasi yinani lama-wavelength adlula iphuzu elifanayo ngomzuzwana owodwa. Uma, lapho igagasi lihamba ngentambo, kune-wavelength ezimbili (ama-crest amabili kanye nama-trough amabili) adlula iphuzu elifanayo, isibonelo iphuzu b, khona-ke imvamisa yegagasi ingu-2 / second noma ama-hertz amabili.
Inkathi (T) yisikhathi esidingekayo ukuze ubude be-wavelength obubodwa budlule iphuzu elifanayo. Uma igagasi lisakazeka ngentambo, kukhona ubude be-wavelength obubodwa (i-crest eyodwa kanye nomugqa owodwa) obudlula iphuzu elifanayo, isibonelo iphuzu b, ngomzuzwana owodwa khona-ke isikhathi segagasi singumzuzwana owodwa.
Isivinini samagagasi (v) = imvamisa x ubude bamagagasi = ubude bamagagasi / inkathi
Isibonelo sezinkinga
Intambo ingamamitha angu-4 ubude. Uma ingxenye eyodwa yentambo ishukunyiswa phezulu naphansi ngamasentimitha angu-30, kuzovela amagagasi ajikelezayo asakazeka ngentambo ngesivinini esingu-1 m/s. Uma kunezintaba ezimbili kanye nemisele emibili eceleni kwentambo, nquma: (a) ubude be-wavelength (b) imvamisa (c) isikhathi (d) ubukhulu
Ingxoxo
(a) Ubude begagasi
Ubude bentambo bungamamitha angu-4 futhi eceleni kwentambo kunezingqimba zamaza ezimbili (amagquma amabili nezigodi ezimbili) ngakho-ke ubude be-wavelength obubodwa = amamitha amabili.
(b) Imvamisa (f)
(c) Isikhathi (T)
T = 1/f = 1/0,5 = imizuzwana emi-2
(d) Ububanzi (A)
Ubukhulu noma ukuphambuka okuphezulu = 30 cm = 0,3 amamitha.
