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:
Ubude obu-1 bune-crest eyodwa kanye nomthamo owodwa . Kunezingqimba zamaza ezi-4 phakathi kuka-A no-B. Ibanga phakathi kuka-A no-B lingamamitha ayi-6 ukuze ubude obu-1 ( λ) = amamitha ayi-6 s / 4 = amamitha ayi-1.5 s.
Isikhathi esidingekayo ukuhamba kusuka ku-A kuya ku-B singamasekhondi ama -2 ukuze isikhathi esidingekayo ukuhamba sibe yi-wavelength engu-1 = isikhathi (T) = 2 sec on ds / 4 = 0.5 sec on ds.
Isibalo sejubane lamagagasi:
v = λ f = λ / T
v = isivinini segagasi , λ = ubude besikhathi , f = imvamisa , T = isikhathi
Isivinini segagasi:
v = amamitha angu-1.5 s / 0.5 se conds
v = 3 amamitha s /se isimo

2. Uma isikhathi esidingekayo ukuhamba kusuka ku-A kuya ku-B singamasekhondi angu-8, nquma ijubane legagasi eliphambeneyo.
Kwaziwa:
Kunezingqimba ezimbili zamaza.
Ubude obungu -1 ( λ) = 2 x 4 amamitha s = 8 amamitha s
Inkathi (T) = 8 se conds / 2 wavelengths = 4 sec on ds / wavelength
Okufunwayo: Isivinini segagasi (v)
Isixazululo:
Ijubane lamagagasi libalwa kusetshenziswa i-equation yejubane lamagagasi:
v = f λ = λ/T
v = amamitha angu-8 s / 4 se conds
v = 2 amamitha s /se isimo
