Question

The side mirrors on cars are convex mirrors. Suppose the side mirror on the driver side of your car has a focal length with a magnitude of 5.10 m and a truck is at a distance of 9.00 m from the mirror. (a) Determine the image distance of the truck. (Include the appropriate positive or negative sign.) 3.64 What is the relationship between the focal length, image distance, and object distance for a spherical mirror? m (b) Determine the magnification for this object distance. (Include the appropriate positive or negative sign.) 1.47 What is the definition for the magnification of a spherical mirror?

Answer 1

a)

From thin lens formula

1/f =1/p +1/i

1/5.1 = 1/(-9)+1/i

i=3.255m

b)

Magnification is given by

M=-i/p =-3.255/(-9)

M=0.3617
