Tambayoyi Misali Game da Raƙuman Haske: Fahimtar Ra'ayi da Amfaninsa
Raƙuman haske wani abu ne na zahiri wanda ke taka muhimmiyar rawa a rayuwar yau da kullun da kuma aikace-aikacen kimiyya daban-daban. Daga sadarwa ta gani zuwa ci gaban fasahar laser, fahimtar raƙuman haske yana da matuƙar muhimmanci. Wannan labarin zai tattauna ainihin manufar raƙuman haske kuma ya ba da misalai na matsaloli don ƙara fahimtar wannan batu.
Asalin Ma'anar Raƙuman Haske
Raƙuman haske nau'in raƙuman lantarki ne da za su iya yaɗuwa ba tare da buƙatar matsakaici ba. Ba kamar raƙuman sauti ba, waɗanda ke buƙatar iska don yaɗuwa, raƙuman haske za su iya tafiya ta cikin injin. Saurin haske a cikin injin yana da daidaito, kimanin mita 299.792.458 a kowace daƙiƙa, ko kuma kimanin kilomita 300.000 a kowace daƙiƙa.
Raƙuman haske suna da siffofi na musamman, waɗanda suka haɗa da tunani, refraction, diffraction, da kuma tsangwama.
1. Tunani: Lokacin da haske ya bugi wani wuri kuma aka mayar da shi baya.
2. Rarrabuwa: Canji a alkiblar haske idan ya ratsa ta iyakokin hanyoyin sadarwa guda biyu daban-daban.
3. Diffraction: Yaɗuwar raƙuman ruwa lokacin da suke ratsawa ta cikin wani ƙaramin rami.
4. Tsangwama: Haɗakar raƙuman haske guda biyu waɗanda zasu iya haifar da tsari mai ginawa ko lalatawa.
Tattaunawa game da Hasken Raƙuman Ruwa
Don amfani da waɗannan ra'ayoyi, bari mu dubi wasu misalai na matsalolin:
Tambaya ta 1: Hankalin Haske
Tambaya: Hasken haske yana buga madubi mai faɗi a kusurwar da ke nuna digiri 30. Menene kusurwar da ke nuna hasken?
Tattaunawa: Dangane da dokar tunani, kusurwar abin da ya faru daidai take da kusurwar tunani. Don haka, idan kusurwar abin da ya faru digiri 30 ne, to kusurwar tunani ma digiri 30 ne.
Amsa: Kusurwar tunani = digiri 30.
Tambaya ta 2: Rarrabuwar Haske
Tambaya: Haske yana ratsawa daga iska (ma'aunin haske n1 = 1) zuwa ruwa (ma'aunin haske n2 = 1,33) a kusurwar da ta kai digiri 45. Menene kusurwar ja da baya?
Tattaunawa: Yi amfani da dokar Snell wadda aka bayyana a cikin dabarar:
n1 zunubi(θ1) = n2 zunubi(θ2)
Da n1 = 1, θ1 = digiri 45, n2 = 1,33. Sannan:
zunubi(θ2) = (n1 zunubi(θ1)) / n2
= zunubi(45°) / 1,33
= 0,707/1,33
. 0,531
Don nemo θ2, muna amfani da sine mai juyawa:
θ2 = arcsin(0,531) ≈ digiri 32,1.
Amsa: Kusurwar refraction ≈ digiri 32,1.
Tambaya ta 3: Tsangwama Mai Sauƙi
Tambaya: A cikin gwajin da Young ya yi na raba rami biyu, haskoki guda biyu masu ma'auni na tsawon nisan nm 600 suna ƙirƙirar tsarin tsangwama a kan allo. Idan nisan da ke tsakanin ramukan biyu shine 0,1 mm kuma nisan da ke tsakanin allon shine mita 2, a tantance nisan da ke tsakanin madaukai biyu masu haske da ke kusa.
Tattaunawa: An bayar da nisan da ke tsakanin haskoki masu haske guda biyu (gefen gefe) a cikin tsarin tsangwama ta hanyar lissafi:
Δy = (λ L) / d
Inda λ shine tsawon tsayi (600 nm = 600 x 10^-9 m), L shine nisa zuwa allon (2 m), kuma d shine nisa tsakanin tsagewar (0,1 mm = 0,1 x 10^-3 m).
Δy = (600 x 10^-9 m 2 m) / (0,1 x 10^-3 m)
= (1200 x 10^-9 m) / (0,1 x 10^-3 m)
= 0,012 m
= 12 mm.
Amsa: Nisa tsakanin madaukai biyu masu haske shine ≈ 12 mm.
Tambaya ta 4: Bambancin Haske
Tambaya: Haske mai tsawon nisan nm 500 yana ratsawa ta cikin wani kunkuntar tsagi mai faɗin mm 0,02. Kayyade kusurwar diffraction don tsari na farko!
Tattaunawa: Ga rami ɗaya, kusurwar diffraction don tsari m ana bayyana ta hanyar lissafi:
sin(θ) = mλ
Ga oda ta farko (m=1), muna maye gurbin:
0,02 x 10^-3 m zunubi (θ) = 1 500 x 10^-9 m
zunubi (θ) = (500 x 10^-9 m) / (0,02 x 10^-3 m)
= 0,025
θ = arcsin(0,025) ≈ digiri 1,43.
Amsa: Kusurwar diffraction ta farko ≈ digiri 1,43.
