Prism - E sebelisetsoa ho arola kapa ho hasanya mahlaseli a khanya.
Tlhaloso ea Sehlahisoa
Prism ke polyhedron e entsoeng ka thepa e bonaletsang (joalo ka khalase, kristale, joalo-joalo). E sebelisoa haholo lisebelisoa tsa optical. Li-prism li ka aroloa ka mefuta e mengata ho latela thepa le ts'ebeliso ea tsona. Mohlala, lisebelisoa tsa spectroscopic, "dispersion prism" e bolisang leseli le kopaneng ho ba spectra hangata e sebelisoa joalo ka prism ea equilateral; ka lisebelisoa tse kang li-periscopes le libonela-hōle tsa libonela-hōle, ho fetola tsela ea leseli ho fetola boemo ba eona ba ho nka litšoantšo ho bitsoa "prism e feletseng". "Reflecting prism" hangata e sebelisa li-prism tse lehlakoreng le letona.
Lehlakore la prism: sefofane seo kganya e kenang le ho tsoa ho sona se bitsoa lehlakore.
Karolo e ka sehloohong ea prism: sefofane se pota-potileng ka lehlakoreng se bitsoa karolo e kholo. Ho ea ka sebopeho sa karolo e kholo, e ka aroloa ka liprism tse khutlo-tharo, li-prism tse lehlakoreng le letona le li-pentagonal. Karolo e ka sehloohong ea prism ke kgutlotharo. Prism e na le libaka tse peli tse refracting, angle pakeng tsa tsona e bitsoa apex, 'me sefofane se shebaneng le tlhōrō ke tlase.
Ho ea ka molao oa refraction, lehlaseli le feta ka har'a prism 'me le kheloha habeli ho ea holimo. Lehlaseli la q pakeng tsa lehlaseli le tsoang le lehlaseli la ketsahalo le bitsoa deflection angle. Boholo ba eona bo khetholloa ke index ea refractive n ea prism medium le angle angle i. Ha ke tsitsitse, maqhubu a fapaneng a khanya a na le li-angles tse fapaneng tsa ho kheloha. Leseling le bonahalang, angle ea ho kheloha ke e kholo ka ho fetisisa bakeng sa leseli la violet, 'me e nyenyane ka ho fetisisa ke ea leseli le lefubelu.
