Solve and illustrate:
1. A beam of light is incident upon a mirror that is
held horizontally. The angle that the light beam
makes with the normal line is 45.0°. What is the
angle of reflection?
2. Now the mirror is tilted at an angle of 30.0°
above the horizontal without changing the
direction of the incident beam. What is now the
angle of incidence? What is the new angle of
reflection?
