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.
