Reference no: EM13998124

For safety reasons, you install a rear-window lens (not a mirror) with a -0.295 m focal length in your van. Before putting the van in reverse, you look through the lens in the rear window and see the image of a person who appears to be 0.336m tall and 0.235 m behind the van.

The actual person (not his or her image) is the object, and the object (person) is behind (outside) the van. The object distance is positive (since it is a real object), and light is traveling from the object (the person), through the lens, and to your eyes (inside the van).

What is the image distance (of the person), s' ?

Use this information to determine the following:

(a) actual distance of the person behind the van

(b) height of the person (Remember that the magnification is related to the distances of the image and object as well as to their sizes.)
