WebIn general, total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other … WebUsing the definition of the critical angle, q C = sin -1 ( n4 / n2 )= sin -1 (1.44/1.480)= 76.65 o. The critical angle for the core-cladding interface is 76.7 o. (b) For total internal reflection to occur, q 3 must be greater than the critical angle. Therefore, q 3 = 90 o - q 2 > q C, so 90 o - q C > q 2, and 90 o -76.65 o = 13.35 o > q 2.
