The homework problem is "An object 26.0 cm in front of a certain lens is imaged 1.60 cm in front of that lens (on the same side as the object). What is the focal length (in centimeters) of this lens"
1/f = 1/di + 1/do
I tried solving based on having distance of object (do) and distance of image (di) so 1/26 + 1/1.6 = 1/f and I solved for f coming up with 1.51 cm. I also tried with -1.6 since they are on the same side coming up with -1.71 and the computer doesn't accept either
