1. The problem statement, all variables and given/known data
A lens placed at the origin with its axis pointing along the x axis produces a real inverted image at x = 24 cm that is twice as tall as the object What is the image distance? 2. Relevant equations m = d'/d 3. The attempt at a solution I thought d=24 cm. and h' = 2h then use m = h'/h to solve for the m. which I got m = 2. then I used m = d'/d 2 = d'/24 d' = 48 cm. I don't know where I did wrong.. please help me.. thanks..
