Homework Statement
A converging lens of focal length 0.246 m forms a virtual image of an object. The image appears to be .933 m from the lens on the same side as the object. What is the distance between the object and the lens?
Homework Equations
1/f = 1/di + 1/do
Since the image is virtual, it would be a negative distance right?
so 1/f = -1/di + 1/do
The Attempt at a Solution
I get do = (.246)(.993)/(.246+.993) = .197157 m
which is wrong..
