Kev piav qhia ntau lawm

Cov looj tsom iav dub tuaj yeem thaiv lub teeb tsis zoo thiab tiv thaiv ob lub qhov muag los ntawm ultraviolet rays. Tag nrho cov no yog vim cov hlau hmoov pom cov khoom siv, uas tuaj yeem "xaiv" lub teeb thaum nws nkag mus. Cov tsom iav xim muaj peev xwm xaiv tau ib feem ntawm lub hnub ci ntawm lub hnub ci vim tias lawv siv cov hmoov hlau zoo heev (hlau, tooj liab, npib tsib xee, thiab lwm yam). Qhov tseeb, thaum lub teeb hits lub lens, lub teeb raug txo raws li cov txheej txheem hu ua "kev cuam tshuam kev cuam tshuam".

Hauv lwm lo lus, thaum qee qhov wavelengths ntawm lub teeb (ntawm no yog hais txog ultraviolet A, ultraviolet B, thiab qee zaus infrared) dhau los ntawm lub lens, lawv yuav tso tseg ib leeg rau sab hauv lub lens, uas yog, nyob rau hauv kev taw qhia ntawm lub qhov muag. Kev sib tshooj ntawm lub teeb nthwv dej tsis yog qhov xwm txheej: kev sib xyaw ua ke ntawm cov peaks ntawm nthwv dej thiab cov troughs ntawm nws cov nthwv dej uas nyob ib sab ua rau kev sib nrig sib tshem tawm. Qhov tshwm sim ntawm kev cuam tshuam cuam tshuam yog nyob ntawm qhov ntsuas qhov ntsuas ntawm lub lens (uas yog, qhov sib txawv ntawm qhov sib txawv thaum lub teeb dhau los ntawm cov khoom sib txawv ntawm huab cua) thiab ntawm lub thickness ntawm lub lens. Feem ntau hais lus, lub thickness ntawm lub lens hloov me ntsis, thaum lub refractive index ntawm lub lens txawv raws li qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg. Thiab looj tsom iav dub yuav tsum tsis txhob sib cuag nrog lub hnub ncaj qha.
