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 … WebThe actual value of the critical angle is dependent upon the two materials on either side of the boundary. For the crown glass-air boundary, the critical angle is 41.1 degrees. For the diamond-air boundary, the …
