Kuki amafi amwe yumva urumuri rukabije?
Ubushakashatsi buherutse gukorwa bwerekanye ko amafi menshi yumva urumuri rwinshi.Abantu ntibafite ubushobozi bwo gutandukanya polarisiyasi numucyo usanzwe.Umucyo usanzwe uranyeganyega mu mpande zose perpendicular yerekeza ku cyerekezo cyurugendo;Nyamara, urumuri rwa polarize runyeganyega mu ndege imwe gusa.Iyo urumuri rugaragajwe nubutaka bwinshi butari ubutare, harimo nubuso bwinyanja, buba bwuzuye polarike kurwego runaka.Ibi birasobanura uburyo indorerwamo yizuba ikora: Zibuza gutambuka gutambitse kugizwe na polarisiyasi hejuru yinyanja, ibyo bikaba bitera urumuri rwinshi, ariko bigatuma ibice byerekanwe bihagaze.
Kudasobanukirwa neza impamvu amafi amwe abasha kumva urumuri rufite polarisiyasi, ubushobozi bwo kumenya urumuri rwa polarize rushobora kuba rufitanye isano nuko iyo urumuri rugaragaye hejuru, nkumunzani uri kuroba, ruba rufite polarike.Amafi ashobora kumenya urumuri rwa polarize afite akarusho mugihe cyo gushaka ibiryo.Iyerekwa rya polarize irashobora kandi kongera itandukaniro riri hagati yumuhigo hafi ya mucyo ninyuma, bigatuma umuhigo woroshye kubona.Ikindi gitekerezo ni uko kugira icyerekezo cya polarize bituma amafi abona ibintu bya kure - inshuro eshatu intera isanzwe igaragara - mugihe amafi adafite ubwo bushobozi akenera urumuri rwinshi.
Kubwibyo, stroboscope yamatara yuburobyi ya MH nta ngaruka mbi ifite ku bushobozi bwo gukurura amafi.
Ibara ry'amatara ya fluorescent, cyane cyane inkoni zaka, arazwi cyane nabarobyi.Kujugunya inkoni yaka mumazi birashobora kumenya niba muri ako gace hari amafi.Mugihe gikwiye, amabara ya fluorescent aragaragara cyane mumazi.Fluorescence ikorwa iyo ihuye nimirasire yumucyo hamwe nuburebure buke.Kurugero, fluorescent yumuhondo igaragara nkumuhondo wera iyo uhuye na ultraviolet, ubururu, cyangwa itara ryatsi.
Fluorescence ibara rya fluorescence iterwa ahanini nurumuri ultraviolet (UV), rutagaragara kuri twe.Abantu ntibashobora kubona urumuri ultraviolet, ariko turashobora kubona uburyo ruzana amabara amwe ya fluorescence.Itara rya Ultraviolet rifite akamaro cyane cyane muminsi yibicu cyangwa imvi, kandi iyo urumuri ultraviolet rumurika kubikoresho bya fluorescent, amabara yabo aragaragara cyane kandi afite imbaraga.Ku munsi w'izuba, ingaruka za fluorescence ni nkeya cyane, kandi birumvikana ko niba nta mucyo uhari, nta fluorescence izaba.
Ubushakashatsi bwerekanye ko amabara ya fluorescent afite intera ndende yumucyo ugaragara kuruta amabara asanzwe, kandi ibishuko hamwe nibikoresho bya fluorescent muri rusange bikurura amafi (kongera itandukaniro no kwanduza intera).Mubyukuri, amabara ya fluorescent afite uburebure buke buke kurenza ibara ryamazi afite intera ndende igaragara.
Nkuko mubibona, urumuri namabara birashobora kugorana cyane.Amafi ntabwo afite ubwenge bwinshi, kandi yibasira umuhigo cyangwa kurigata nkimwe cyangwa nyinshi mumyitwarire yimitekerereze itera moteri.Ibi bitera imbaraga birimo kugenda, imiterere, amajwi, itandukaniro, impumuro, isura, nibindi bintu tutazi.Nibyo, dukeneye gusuzuma izindi mpinduka nkigihe cyumunsi, imiraba nandi mafi cyangwa ibidukikije byamazi.
Rero, iyo urumuri rumwe rwa UV rugeze kumazi, bituma zimwe muri plankton zigaragara neza mumaso y amafi, bigatuma zegera.
Nigute ushobora gukora itara ryo kuroba rirerire kandi ryiza gukurura amafi, ibi ntabwo aribyo gusauruganda rutunganya uburobyiikeneye gukemura ikibazo, kuri capitaine uburyo ukurikije imiterere yinyanja yaho.Uhujije n’imigezi yo mu nyanja, ubushyuhe bwinyanja kugirango uhindure ibara ryiza ryiza, nka: umuheto, ubwato, inyuma bizongeramo andi mabara yoroheje kugirango bivange ubufatanye.Icyo tuzi nuko abakapiteni bamwe bazashyiramo amatara yuburobyi cyangwaitara ry'ubururumumatara yera kuroba.MuLED itara, ongera igice cya ultraviolet spektr,
