Kukwera kwa refractive index ya disolo, lens imakhala yocheperapo komanso yovuta kwambiri.Zoonadi, kuchuluka kwa refractive index, kumakhala bwino, komanso kumakhala kokwera mtengo kwambiri.Ngati mukufuna kuti zifanane kwambiri woonda magalasi, osati ndi index refractive, komanso ndi chimango kukula ndi wophunzira mtunda.
Ndiye mfundo ndiyakuti, mumasankha bwanji refractive index ya mandala?
