The Total Internal Reflection Concept Builder includes three activities that target student understanding of the requirements for total internal … WebThe smallest angle of incidence at which total internal reflection occurs is called the critical angle, qc. Using Snell’s law, n1 Sinqθ i = n2 Sin(90°) = n2. From this, qc = Sin-1 (n2/n1). These diagrams illustrate two different cases of refraction. Total internal refraction is depicted in the sketch on the right. WebTotal internal reflection occurs for any incident angle greater than the critical angle θc, and it can only occur when the second medium has an index of refraction less than the first. Note the above equation is written for a light ray that travels in medium 1 and reflects from medium 2, as shown in the figure. cost of living infographic
