WebTotal Internal Reflection. When light is incident upon a medium of lesser index of refraction, the ray is bent away from the normal, so the exit angle is greater than the incident angle.Such reflection is commonly called "internal reflection".The exit angle will then approach 90° for some critical incident angle θ c, and for incident angles greater than the … WebAs the angle of incidence increases beyond the critical angle, the conditions of refraction can no longer be satisfied, so there is no refracted ray, and the partial reflection becomes …
