Question
A certain slide projector has a 100 mm focal length lens. (a) How far away is the screen, if a slide is placed 103 mm from the lens and produces a sharp image? (b) If the slide is 24.0 by 36.0 mm, what are the dimensions of the image? Explicitly show how you follow the steps in the Problem- Solving Strategy for lenses.
1. $3.43 \textrm{ m}$
2. $l_\textrm{i} = 0.800 \textrm{ m}$, $w_\textrm{i} = 1.20 \textrm{ m}$
