N’chifukwa chiyani magetsi oyaka magalimoto anasankha mitundu itatu yofiira, yachikasu ndi yobiriwira?

Kuwala kofiira ndi "imani", kuwala kobiriwira ndi "pitani", ndipo kuwala kwachikasu kumayatsa "pitani mwamsanga".Iyi ndi njira yamagalimoto yomwe takhala tikuiloweza kuyambira tili ana, koma mukudziwa chifukwa chakemagalimoto akuthwanima nyaliamasankha zofiira, zachikasu, ndi zobiriwira m’malo mwa mitundu ina?

Mtundu wa magetsi oyaka magalimoto

Tikudziwa kuti kuwala kowoneka ndi mawonekedwe a mafunde a electromagnetic, omwe ndi gawo la ma electromagnetic spectrum omwe amatha kuwonedwa ndi maso a munthu.Kwa nyonga yofananayo, kutalika kwa utali wa mafunde, sikumamwazikana, ndipo kumapita kutali.Mafunde a mafunde a electromagnetic omwe maso a anthu wamba amatha kuwona ali pakati pa 400 ndi 760 nanometers, komanso kutalika kwa kuwala kwa ma frequency osiyanasiyana kumasiyananso.Pakati pawo, kutalika kwa mawonekedwe a kuwala kofiira ndi 760 ~ 622 nanometers;kutalika kwa mawonekedwe a kuwala kwachikasu ndi 597 ~ 577 nanometers;kutalika kwa mawonekedwe a kuwala kobiriwira ndi 577 ~ 492 nanometers.Choncho, kaya ndi magetsi ozungulira magalimoto kapena muvi wodutsa muvi, magetsi amawayika motsatira ndondomeko ya zofiira, zachikasu, ndi zobiriwira.Pamwamba kapena kumanzere kwambiri kumayenera kukhala kofiira, pomwe kuwala kwachikasu kumakhala pakati.Pali chifukwa cha makonzedwe awa - ngati magetsi ndi osakhazikika kapena dzuwa liri lamphamvu kwambiri, dongosolo lokhazikika la magetsi owonetserako ndilosavuta kuti dalaivala azindikire, kuti atsimikizire kuyendetsa galimoto.

Mbiri yamagalimoto akuyaka magalimoto

Magetsi oyaka akale kwambiri amawunikira masitima apamtunda osati magalimoto.Chifukwa chakuti chofiira chili ndi utali wautali kwambiri wa mafunde pa sipekitiramu yooneka, chikhoza kuwonedwa patali kuposa mitundu ina.Chifukwa chake, imagwiritsidwa ntchito ngati chowunikira pamasitima apamtunda.Panthaŵi imodzimodziyo, chifukwa cha mbali zake zokopa maso, zikhalidwe zambiri zimawona kufiira kukhala chizindikiro cha ngozi.
