Saurin raƙuman ruwa masu wucewa - matsaloli da mafita
1.
Idan tazarar lokacin da ake buƙata don tafiya daga A zuwa B daƙiƙa 2 ne, a ƙayyade saurin raƙumin da ke ratsawa.
An sani:
Nisa AB = mita 6 a kowace daƙiƙa
Tazarar lokaci AB = daƙiƙa 2
Ana so: Gudun raƙuman ruwa masu wucewa
Magani:
Raƙuman ruwa guda ɗaya yana da katanga ɗaya da kuma tafki ɗaya . Akwai raƙuman ruwa guda huɗu tsakanin A da B. Nisa tsakanin A da B mita 6 ne don haka raƙuman ruwa guda ɗaya ( λ) = mita 6 s / 4 = mita 1.5 s.
Tazarar lokacin da ake buƙata don tafiya daga A zuwa B shine daƙiƙa 2 don haka tazarar lokacin da ake buƙata don tafiya 1 tsawon rai = lokaci (T) = 2 sec c akan ds / 4 = 0.5 sec c akan ds.
Daidaiton saurin raƙuman ruwa:
v = λ f = λ / T
v = saurin raƙuman ruwa , λ = tsawon ruwa , f = mita , T = lokaci
Gudun raƙuman ruwa:
v = mita 1.5 a minti 0.5 / yanayin zafi
v = mita 3 a cikin s / se

2. Idan tazarar lokacin da ake buƙata don tafiya daga A zuwa B daƙiƙa 8 ne, a ƙayyade saurin rabe-raben raƙuman ruwa.
An sani:
Akwai nau'ikan wavelength guda biyu.
Raƙuman ruwa 1 ( λ ) = mita 2 x 4 s = mita 8 s
Lokaci (T) = 8 sec conds / 2 raƙumi = 4 sec c akan ds / raƙumi
Ana so: Gudun raƙuman ruwa (v)
Magani:
Ana ƙididdige saurin raƙuman ta amfani da lissafin saurin raƙuman:
v = f λ = λ/T
v = mita 8 a minti 4 / yanayin zafi
v = mita 2 a cikin s / se
