Scholars work through three different activities applying their knowledge of total internal reflection (TIR). First, they simply identify which diagrams create TIR and which don't. Next, they match different types of boundary behaviors considering the angle of incidence and the critical angle. Finally, they compare two media and identify the correct diagram to achieve TIR.
