An object is 14 cm in front of a concave mirror, and the image is 5.8 cm behind the mirror. what is focal length?
Added by Antonio T.
Step 1
The object distance (\(d_o\)) is 14 cm, and the image distance (\(d_i\)) is -5.8 cm. The image distance is negative because the image is formed behind the mirror, which is a convention for concave mirrors. Show more…
