Radius of curvature imagwirizana mwachindunji ndi Sagitta, yomwe imatchedwa Sag mumakampani opanga kuwala.M'mawu a geometric, Sagitta imayimira mtunda kuchokera pakati pa arc mpaka pakati pa maziko ake.Mu optics, Sag imagwira ntchito ku kupindika kopingasa kapena kopindika ndipo imayimira mtunda wapakati pakati pa vertex (malo okwera kwambiri kapena otsika kwambiri) popindika ndi nsonga yapakati ya mzere wokokedwa mokhotakhota kuchokera kumphepete kumodzi kwa optic mpaka zina.Chithunzi pansipa chikuwonetsa chithunzi cha Sag.
Chithunzi 5: Zithunzi za Sag
Sag ndiyofunikira chifukwa imapereka malo apakati a utali wopindika, motero amalola opanga kuyika bwino ma radius pa optic, komanso, kukhazikitsa pakati ndi m'mphepete makulidwe a kuwala.Podziwa kutalika kwa kupindika, komanso kukula kwa mawonekedwe a optic, Sag imatha kuwerengedwa motsatira njira zotsatirazi.
