Question

A mirror on the passenger side of your car is convex and has a radius of curvature with magnitude 18.0cm.

Part A

Another car is behind your car, 9.0m from the mirror, and this car is viewed in the mirror by your passenger. If this car is 1.5m tall, what is the height of the image?

y? =

  m  

Part B

The mirror has a warning attached that objects viewed in it are closer than they appear. Why is this so?

Answer 1

Part APart B

The mirror makes object look smaller at the cost of a wider field view. As we are accustomed to the thinking that "smaller the object looks, farther it is from the observer". That's why the warning is there, to point out the fact that the mirror image does not give the correct estimate about the distance of object.
