CHAPTER 17 Reflection and Mirrors
5. Two plane mirrors are positioned at right angles to one another. A ray of light strikes one mirror at an angle of 30° to the normal. It then reflects toward the second mirror. What is the angle of reflection of the light ray off the second mirror?! r1!! i1! 30°! i2! 90° "! r1! 90° " 30° ! 60° Section Review 17.1 Reflection from Plane ...
