Iyini i-prism ehlakazayo?
Context:Ku-optics, i-dispersive prism i-optical prism esetshenziselwa ukusabalalisa ukukhanya, okungukuthi, ukuhlukanisa ukukhanya kube yizingxenye zayo ze-spectral (imibala yomnyama). Amaza ahlukahlukene (imibala) yokukhanya ayohlanekezelwa yi - prism ngama - angle ahlukahlukene. Lokhu kubangelwa ukuthi inkomba yokuqhekeka kwezinto ze-prism iyahlukahluka ngobude begagasi (ukusabalala). Ngokuvamile, ubude bamaza obude (obomvu) bunokuphambuka okuncane kunobude bamaza obufushane (obuhlaza okwesibhakabhaka). Ukuhlakazwa kokukhanya okumhlophe kube yimibala ngeprism kwaholela uSir Isaac Newton ukuba aphethe ngokuthi ukukhanya okumhlophe kwakuyinhlanganisela yemibala ehlukahlukene.
I-dispersive prism i-optical prism ehlakaza ubude bamaza obuhlukile bokukhanya kuma-angle ahlukene. Lapho ukukhanya okumhlophe kukhanyiswa ngephrism ehlakazayo kuyohlukana kube imibala ehlukahlukene yomnyama.
