Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface.
For example, total internal reflection prisms are used in combination with a series of lenses in binoculars (Figure 6). In some cases, different types of prisms are used to change or rotate the atti-tude of images (Figure 7). A single 45° right-angle prism can be used to deflect an image 90° or 180°. Right-angle prisms are used in many laser applications. Sample Problem 2 An incident ray of

Total internal reflection occurs when light is passing through a medium (call it 1) like glass or plastic with an index of refraction n1. Outside this material is a medium like air (call it 2) with an index of refraction n2.
