What is the focal length of a lens that produces a real image three times as large as the object if the distance between image and object is 1.0m?
Added by Mark T.
Step 1
We know that the image is real and three times as large as the object, which means the magnification \( m = -3 \) (negative because the image is real and inverted). The distance between the image and the object is 1.0 m. Show more…
