Isivinini samagagasi adlulayo - izinkinga nezixazululo
1.
Uma isikhathi esidingekayo ukuhamba kusuka ku-A kuya ku-B singamasekhondi ama-2, nquma ijubane legagasi eliphambeneyo.
Kwaziwa:
Ibanga AB = amamitha ayi-6 ngomzuzwana
Isikhawu sesikhathi AB = imizuzwana emi-2
Okufunwayo: Isivinini samagagasi adlulayo
Isixazululo:
1 ubude bamaza ine-crest eyodwa kanye nomkhombe owodwa. Kunama-wavelength amane phakathi kuka-A no-B. Ibanga phakathi kuka-A no-B lingamamitha ayi-6 ngakho-ke lokho kuyi-wavelength eyodwa (λ) = Imitha ye-6s / 4 = amamitha angu-1.5s.
Itisikhathi esidingekayo ukuhamba kusuka ku-A kuya ku-B yi 2 imizuzwana ukuze isikhathi esidingekayo sokuhamba ubude obungu-1 = isikhathi (T) = 2 seconds / 4 = 0.5 seconds.
Isibalo sejubane lamagagasi:
v = λ f = λ / T
v = isivinini segagasi, λ = ubude bamaza, f = imvamisa, T = pisikhathi
Isivinini segagasi:
v = amamitha angu-1.5s / 0.5 seizimo
v = amamitha angu-3s/seisimo
2. Uma isikhathi esidingekayo ukuhamba kusuka ku-A kuya ku-B singamasekhondi angu-8, nquma ijubane legagasi eliphambeneyo.
Kwaziwa:
Kunezingqimba ezimbili zamaza.
1 ubude bamaza (λ) = 2 x 4 amamithas = 8 imithas
Isikhathi (T) = 8 seizimo / 2 ama-wave = 4 seconds / ubude bamaza
Kufunwa: Isivinini segagasi (V)
Isixazululo:
Ijubane lamagagasi libalwa kusetshenziswa i-equation yejubane lamagagasi:
v = f λ = λ/T
v = amamitha angu-8s / 4 seizimo
v = amamitha angu-2s/seisimo
