6. 'n Silindriese optiese vesel het brekingsindeks van 1,40 en die van die omhulsel 1,25. Lig skyn in die vesel in teen 'n (3) hoek 0 soos aangedui. Watter maksimum invalshoek 0 sal maak dat invallende lig ten volle deur die vesel sal voortplant deur totale interne weerkaatsing by die velse/omhulsel skeidingsvalk? A cylindrical fiber optic cable has index of refraction 1,40 and that of its surrounding cladding 1,25. Light is shown into the fiber at an angle of 0 as omhu indicated. What maximum incident angle 0 will ensure that incident light Isel / will be fully transmitted along the fiber through total internal reflection at claddi e vesel / the fiber/cladding interface? ng fiber A. 270 B. 380 C. 470 D. 570 E. 630
