Yintoni iprism yokusabalalisa?
Context:Kwi-optics, i-dispersive prism yi-optical prism esetyenziselwa ukusasaza ukukhanya, oko kukuthi, ukwahlula ukukhanya kwiinxalenye zayo ze-spectral (imibala yomnyama). Ubude bamaza obahlukeneyo (imibala) yokukhanya iya kuphambukiswa yiprism kwii-engile ezahlukeneyo. Oku kungumphumo wezinto zeprism ze-index of refraction ezihluka kunye nobude be-wave (ukusabalalisa). Ngokubanzi, ubude bamaza obude (obomvu) bunokuphambuka okuncinci kunobude bamaza obufutshane (oblue). Ukusasazeka kokukhanya okumhlophe kube yimibala ngeprism kwakhokelela uMhlekazi uIsaac Newton ekubeni agqibe kwelokuba ukukhanya okumhlophe kwakunomxube wemibala eyahlukahlukeneyo.
Iprism yokusabalalisa iprism ebonakalayo eyahlula ubude bemitha eyahlukeneyo yokukhanya kwii-engile ezahlukeneyo. Xa ukukhanya okumhlophe kukhanyiswa nge prism esasazekayo kuya kwahlukana ibe yimibala eyahlukeneyo yomnyama.
