Tsanangudzo yemafungu anochinjika
Mafungu anotenderera mafungu ane gwara rekupararira rakanangana negwara rekuzunguzika kwechinhu chaanopfuura nacho.
Mienzaniso yemafungu anochinjika
Muenzaniso wewave inochinjika iwave iri patambo kana waya. Kana wave iri patambo ichifamba kubva kuruboshwe kuenda kurudyi, tambo yacho inokwira nekudzika, yakatarisana nekwainobva mafungu.
Zvikamu zvemafungu anochinjika
Museve mutsvuku uri kurudyi unoratidza mafambiro emafambiro efungu. Miseve mitsvuku iri kumusoro nekudzika inoratidza mafambiro echikamu chimwe nechimwe chetambo.
A (amplitude) = kutsauswa kwakanyanya kwetambo
Lambda (hurefu hwemafungu) = daro riri pakati pemakomo maviri akatevedzana = daro riri pakati pemafungu maviri akatevedzana = daro riri pakati pemapoinzi maviri akatevedzana ehurefu hwakafanana. Pfungwa iripo ndeyekuti hurefu humwe hwemafungu hune goko rimwe chete negoko rimwe chete.
a – b = chikomo chemafungu
b – c = mupata wemafungu
Frequency (f) yemafungu inhamba yemafungu anopfuura poindi imwe chete musekondi imwe chete. Kana, kana mafungu achifamba netambo, paine mafungu maviri (maburi maviri nematafura maviri) anopfuura poindi imwe chete, semuenzaniso poindi b, saka frequency yemafungu i2 / second kana 2 hertz.
Nguva (T) inguva inodiwa kuti wavelength imwe ipfuure poindi imwe chete. Kana wave ikapararira ichitevedza tambo, paine wavelength imwe (crest imwe netrough imwe) ichipfuura poindi imwe chete, semuenzaniso poindi b, musekondi imwe chete, ipapo wave period i1 second.
Kumhanya kwemafungu (v) = frequency x wavelength = wavelength / period
Muenzaniso wezvinetso
Tambo yakareba mamita mana. Kana mugumo mumwe wetambo ukasimudzwa kumusoro nekudzika masendimita makumi matatu, mafungu anotenderera anobuda achitevedza tambo nekumhanya kwe1 m/s. Kana paine zvikomo zviviri uye mapombi maviri ari patambo, sarudza: (a) kureba kwehurefu (b) frequency (c) nguva (d) amplitude
Kukurukurirana
(a) Kureba kweMafungu
Kureba kwetambo iyi mamita mana uye padivi petambo iyi pane marefu maviri ewavelength (makomo maviri nemipata miviri) saka wavelength imwe chete = mamita maviri.
(b) Kuwanda (f)
(c) Nguva (T)
T = 1/f = 1/0,5 = masekondi maviri
(d) Kukura kwenzvimbo (A)
Kukura kwakanyanya kana kutsauka = 30 cm = 0,3 metres.
