Liwiro la mafunde opingasa - mavuto ndi mayankho
1.
Ngati nthawi yofunikira yoyendera kuchokera ku A kupita ku B ndi masekondi awiri, dziwani liwiro la mafunde opingasa.
Zodziwika:
Distance AB = mamita 6s
Time imeneyi AB = 2 masekondi
SE basi: Liwiro la mafunde opingasa
Yankho:
1 timaganiza ili ndi kapu imodzi ndi chikho chimodzi. Pali mafunde anayi pakati pa A ndi B. Mtunda pakati pa A ndi B ndi mamita 6 kotero kuti ndi mafunde amodzi (λ) = Mphindi wa 6s / 4 = mamita 1.5s.
Tnthawi yofunikira yoyendera kuchokera ku A kupita ku B ndi 2 masekondi kotero kuti nthawi yofunikira yoyendera ndi 1 wavelength = nthawi (T) = 2 seconds / 4 = 0.5 seconds.
Kuyerekeza kwa liwiro la mafunde:
v = λ f = λ / T
v = liwiro la mafunde, λ = timaganiza, f = pafupipafupi, T = pnthawi
Liwiro la mafunde:
v = mamita 1.5s / 0.5 semikhalidwe
v = mamita 3s/sechikhalidwe
2. Ngati nthawi yofunikira kuti muyende kuchokera ku A kupita ku B ndi masekondi 8, dziwani liwiro la mafunde opingasa.
Zodziwika:
Pali ma wavelength awiri.
1 timaganiza (λ) = 2 x 4 mamitas = 8 mitas
Nyengo (T) = 8 semikhalidwe / 2 kutalika kwa kutalika = 4 seconds / timaganiza
Akufuna: Liwiro la mafunde (v)
Yankho:
Liwiro la mafunde limawerengedwa pogwiritsa ntchito equation ya liwiro la mafunde:
v = f λ = λ/T
v = mamita 8s / 4 semikhalidwe
v = mamita 2s/sechikhalidwe
