Question

The side mirrors on cars are convex mirrors. If the side mirror on the driver side of your car has a focal length with a magnitude of 8.40 m and a truck is at a distance of 8.00 m from the mirror, determine the following. (a) image distance of the truck (Include the appropriate positive or negative sign.) -7.92 Incorrect: Your answer is incorrect. What is the relationship between the focal length, image distance, and object distance for a spherical mirror? m (b) magnification for this object distance (Include the appropriate positive or negative sign.)

Explanation / Answer

relation ship f,di,do:1/f=1/do+1/di

f=8.40m

do=8m

1/8.40=1/8-1/di

di=-168m

(b)m=-di/do

m=56

m is positive

di is negative indicates that image is virtual image located behind the mirror.
