25.2 Exercise 1

Avg difficulty 2.5

An object is 2 meters in front of a flat mirror. Ray 1 from the object travels in a direction toward the mirror and normal to the mirror’s surface. Ray 2 from the object travels at an angle of 5° from the direction of ray 1, and it also reflects off the mirror’s surface. At what distance behind the mirror do these two reflected rays appear to converge to form an image?

  1. 0.2 m
  2. 0.5 m
  3. 2 m
  4. 4 m
