A beam of light is traveling from a region of a higher index of refraction to a region of a lower index of refraction. It strikes the boundary of the refracting surface at an angle greater than the critical angle. a. What is the angle of refraction? b. What happens to the direction of the incident light after striking the refracting surface? c. Name the phenomenon described in the problem.

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
