Refraction Problem
I'm having trouble figuring out how to solve or even start this problem, can someone please help me?
A converging lens (f=25.0cm) is used to project an image of an object onto a screen. The object and the screen are 125 cm apart, and between them the lens can be placed at either of two locations. Find the two objects distances.
My only thought would be to maybe use the thinlens equation 1/do + 1/di = 1/f to find the di, but then I'm not sure how that would help me find where the 2 lens are.
