1. The problem statement, all variables and given/known data A magnifier has a magnification of 9× How far from the lens should an object be held so that its image is seen at the near-point distance of 25 cm? Assume that your eye is immediately behind the lens. Express your answer to two significant figures and include the appropriate units. 2. Relevant equations M = Di/Do M = 9 Di = 25 cm Do = ? 3. The attempt at a solution I thought this problem would be straight forward. Just solve for Do so I ended up with Do = Di / M Do = 25 cm / 9 which i i though equals 2.8 cm. But it is wrong. Where am i messing up?
