12 The diagram shows two blocks of a material whose critical angle is 40°. In block A, the
ray strikes the inner surface with an angle of incidence of 30°. In block B, the ray's
angle of incidence is 50°.
a Copy and complete each diagram to show what happens when the ray strikes the surface.
Use the diagrams to explain what is meant by total internal reflection.
