The image behind a convex mirror (radius of curvature = 71 cm) is located 24 cm from the mirror.
(a) Where is the object located?

• physics -

The focal length of the mirror is
f = -R/2 = -35.5 cm

The image location is

Di = -24 cm,
since it behind the mirror.

Use the basic equation:

1/Do + 1/Di = 1/f = -1/35.5

1/Do = 1/24 - 1/35.5

Solve for object distance Do
