Total internal reflection occurs

WebThis effect is called total internal reflection, and occurs whenever the angle of incidence exceeds the critical angle. Now when , we have , and so . It follows from Eq. that (349) ... Total internal reflection enables light to be transmitted inside thin glass fibers. The light is internally reflected off the sides of the fiber, and, ... WebWhy does total internal reflection happen? Why does total internal reflection happen? TIR occurs because the angle of refraction reaches a 90-degree angle before the angle of incidence reaches a 90-degree angle. The only way for the angle of refraction to be greater than the angle of incidence is for light to bend away from the normal.
