Haka kuma ana iya bambanta raƙuma zuwa raƙuma masu ratsawa da kuma masu tsayi bisa ga alkiblar juyawar barbashi a cikin matsakaici.
Misalan Ka'idojin Raƙuman Ruwa
Ka'idar Maɗaukaki
Ka'idar superposition ta bayyana cewa lokacin da raƙuman ruwa biyu ko fiye suka haɗu a cikin wani matsakaici, tsangwama da ke faruwa a wannan lokacin shine jimlar ƙarfin kowane raƙuman ruwa. Wannan ƙa'ida tana da mahimmanci don fahimtar abubuwan da ke faruwa a cikin tsangwama.
Matsalar Misalin Matsayin Matsala:
Raƙuman ruwa guda biyu na sinusoidal suna haɗuwa a wani wuri a saman ruwa tare da girman A1 = 3 cm da A2 = 4 cm, bi da bi. Idan waɗannan raƙuman ruwa guda biyu suna cikin mataki, a tantance girman raƙuman ruwa da suka haifar.
Amsa:
Tunda dukkan raƙuman ruwa suna cikin lokaci, girman raƙuman ruwa da suka biyo baya shine jimlar girman duka biyun:
\[ A_{\text{total}} = A_1 + A_2 = 3 \, \text{cm} + 4 \, \text{cm} = 7 \, \text{cm} \]
Dokar Snell
Dokar Snell ta shafi raguwar raƙuman ruwa idan suka shiga wani yanayi daban, misali daga iska zuwa ruwa. Wannan yana bayyana ta hanyar dabarar:
\[n_1 \sin \theta_1 = n_2 \sin \theta_2 \]
inda \(n_1 \) da \(n_2 \) su ne fihirisar haske na matsakaici na 1 da 2, kuma \(\theta_1 \) da \(\theta_2 \) su ne kusurwoyin faruwa da kuma raguwar haske.
Tambayoyi Misali Game da Rage Ragewa:
Hasken haske yana tafiya daga iska (mai nuna haske = 1) kuma yana shiga ruwa (mai nuna haske = 1.33) a kusurwar da ta kai digiri 30. Kayyade kusurwar mai nuna haske a cikin ruwa.
Amsa:
Amfani da dokar Snell:
\[ 1 \cdot \sin(30^\circ) = 1.33 \cdot \sin(\theta_2) \]
\[ \sin(30^\circ) = 0.5 \]
\[ 0.5 = 1.33 \cdot \sin(\theta_2) \]
\[ \sin(\theta_2) = \frac{0.5}{1.33} \kimanin 0.376 \]
\[ \theta_2 = \sin^{-1}(0.376) \kimanin 22.2^\circle \]
Yanayin Diffraction
Diffraction shine lanƙwasa raƙuman ruwa lokacin da suka haɗu da cikas kuma suka ratsa ta cikin ƙananan gibi, tare da wannan lamari ya fi bayyana idan girman gibin ya yi daidai da tsawon tsayi.
Misalan Tambayoyi game da Diffraction:
Raƙuman sauti masu tsawon mita 0,5 suna ratsawa ta cikin wani tsagi mai faɗin mita 1. Yi bayani game da yadda wannan zai shafi bambancin raƙuman.
Amsa:
Saboda faɗin tsagewar ya fi tsayin ...
Raƙuman lantarki
Raƙuman lantarki (EM) sun haɗa da raƙuman rediyo, microwaves, hasken infrared, hasken da ake iya gani, hasken ultraviolet, hasken X, da kuma raƙuman gamma. Ba kamar raƙuman injina ba, raƙuman EM ba sa buƙatar wani abu da zai iya yaɗuwa.
Dokar Planck
Sau da yawa ana iya kallon lamarin raƙuman lantarki daga mahangar kimiyyar lissafi ta zamani, kamar dokar Planck wadda ta bayyana cewa kuzarin proton yana daidai da mitarsa:
\[ E = h \cdot f \]
inda \(E \) shine makamashi, \(h \) shine madaidaitan Planck (\(6.626 \times 10^{-34} \, \text{Js}\)), kuma \(f \) shine mita.
Misalan Tambayoyi game da Raƙuman Wutar Lantarki:
Idan yawan hasken ultraviolet shine \(8 \sau 10^{14} \, \text{Hz}\), menene kuzarinsa?
Amsa:
\[ E = 6.626 \sau 10^{-34} \, \text{Js} \sau 8 \sau 10^{14} \, \text{Hz} = 5.301 \sau 10^{-19} \, \text{J} \]

Daga ƙa'idodin superposition zuwa refraction zuwa diffraction, suna ba da haske game da yadda raƙuman ruwa ke hulɗa da muhallinsu da kuma tasirin abubuwan da muke gani.
Ta hanyar misalan da aka gabatar, za mu iya samun fahimtar yadda za a iya amfani da waɗannan ka'idoji, yayin da kuma za mu ƙarfafa fahimtarmu game da ra'ayin raƙuman ruwa gaba ɗaya.
