Magnification produced by a rear view mirror fitted in vehicles

(a) is less than one

(b) is more than one

(c) is equal to one

(d) can be more than or less than one depending upon the position of the object in front of it

 

Answer

  • A convex lens is used in rear view mirrors to provide virtual, erect images of the traffic coming from behind in a car. 
  • A convex mirror always produces a diminished image.
  • This is also why rear view mirrors come with the warning “objects in this mirror may be closer than they appear”. 
  • Thus, the magnification of a rear view mirror is m < 1
