Intangiriro kuri common spectra
1. Urumuri rwa RGB: Muri make, ni urumuri rusanzwe buri wese abona mu buzima bwe bwa buri munsi. R/G/B ihagarariye amabara atatu y'ingenzi y'urumuri rugaragara: umutuku/icyatsi/ubururu. Urumuri buri wese ashobora kubona rugizwe n'aya matara atatu. Mu buryo butandukanye, amafoto yafashwe muri ubu buryo bw'urumuri ntatandukanye n'ayafashwe ako kanya hifashishijwe terefone igendanwa cyangwa kamera.
2. Urumuri ruzunguruka hamwe n'urumuri ruzunguruka hamwe
Kugira ngo dusobanukirwe uruhare rw'urumuri rwa polarized mu gutahura uruhu, tugomba kubanza gusobanukirwa imiterere y'urumuri rwa polarized: amasoko y'urumuri rwa polarized parallel ashobora gukomeza reflection ya specular no kugabanya reflection ya diffuse; urumuri rwa polarized cross-polarized rushobora kugaragaza reflection ya diffuse no gukuraho reflection ya specular. Ku ruhu, ingaruka za reflection ya specular zigaragara cyane bitewe n'amavuta yo hejuru, bityo mu buryo bwa parallel polarized light, biroroha kubona ibibazo by'uruhu bitabangamiye urumuri rwa diffuse rwimbitse. Mu buryo bwa cross-polarized light, specular reflection light ku ruhu ishobora kuyungururwa burundu, kandi urumuri rwa diffuse reflection mu bice byimbitse by'uruhu rushobora kugaragara.
3. Urumuri rwa UV
Urumuri rwa UV ni incamake y'urumuri rwa Ultraviolet. Ni igice kitagaragara cy'uburebure bw'urumuri rwa ultraviolet ruto ugereranyije n'urumuri rugaragara. Uburebure bw'uburebure bw'urumuri rwa ultraviolet rukoreshwa n'icyuma gipima urumuri ruri hagati ya 280nm-400nm, bihuye na UVA isanzwe yumvikana (315nm-280nm) na UVB (315nm-400nm). Imirasire ya ultraviolet iri mu nkomoko y'urumuri abantu bahura nayo buri munsi yose iri muri ubu burebure bw'urumuri, kandi kwangirika k'uruhu buri munsi biterwa ahanini n'imirasire ya ultraviolet y'ubu burebure bw'uru. Iyi ni nayo mpamvu abarenga 90% (wenda 100% mu by'ukuri) b'ibikoresho bipima uruhu biri ku isoko bifite uburyo bw'urumuri rwa UV.
Ibibazo by'uruhu bishobora kugaragara munsi y'urumuri rutandukanye
1. Ikarita y'urumuri ya RGB: Igaragaza ibibazo ijisho ry'umuntu risanzwe rishobora kubona. Muri rusange, ntabwo ikoreshwa nk'ikarita yo gusesengura ubwimbitse. Ikoreshwa cyane cyane mu gusesengura no kwerekana ibibazo mu bundi buryo bw'urumuri. Cyangwa muri ubu buryo, banza wibande ku kumenya ibibazo bigaragazwa n'uruhu, hanyuma ushake impamvu z'ibibazo bihuye nabyo mu mafoto mu buryo bw'urumuri rwa cross-polarized na UV hakurikijwe urutonde rw'ibibazo.
2. Umucyo uhuza imiterere y'urumuri: ukoreshwa cyane cyane mu kureba imirongo mito, imyenge n'utudomo ku ruhu.
3. Umucyo unyuranyije n'amabara: Reba uburyo umubiri ubyimba, ubushyuhe, gutukura n'amabara yo hejuru munsi y'uruhu, harimo ibimenyetso by'ibiheri, utudomo, ubushyuhe bw'izuba, n'ibindi.
4. Umucyo wa UV: cyane cyane kureba ibiheri, utudomo twinshi, ibisigazwa bya fluorescent, imisemburo, dermatitis ikabije, no kureba ukwiyongera kwa Propionibacterium neza cyane munsi y'uburyo bw'urumuri rwa UVB (urumuri rwa Wu).
Ibibazo Bikunze Kubazwa
Q: Umucyo wa ultraviolet ni urumuri rutagaragara ku jisho ry'umuntu. Kuki ibibazo by'uruhu bishobora kugaragara munsi y'urumuri rwa ultravioletisesengura ry'uruhu?
A: Ubwa mbere, kubera ko uburebure bw'urumuri rw'ikintu buruta uburebure bw'urumuri rw'izuba, nyuma y'uko uruhu rufata urumuri rw'urumuri rw'izuba rugufi hanyuma rukagaragaza urumuri rusohoka, igice cy'urumuri rugaragara ku ruhu gifite uburebure bw'urumuri kandi rwabaye urumuri rugaragara ku jisho ry'umuntu; icya kabiri imirasire ya Ultraviolet nayo ni imiraba ya electromagnetic kandi ifite impinduka, bityo iyo uburebure bw'urumuri rw'ikintu buhuye n'uburebure bw'urumuri rw'izuba rucanye ku buso bwarwo, hazagaragara harmonic resonance, bigatuma habaho isoko nshya y'urumuri rw'izuba. Iyo iri soko ry'urumuri rigaragara ku jisho ry'umuntu, rizafatwa n'icyuma gipima. Urugero rworoshye kumva ni uko ibintu bimwe na bimwe mu bihangano byo kwisiga bidashobora kubonwa n'ijisho ry'umuntu, ariko bihinduka fluoresce iyo bihuye n'urumuri rw'izuba.
