Suppose you point a pinhole camera at a 15-m-tall tree that is 75m away.
(a) If the film is 22cm behind the pinhold, what will be the size of the tree's image on the film?
(b) if you would like the image to be larger, should you get closer to the tree or farther from the tree? explain.
(c) if you had time, you could make the image larger by rebuilding the camera, changing the length or pinhole size. What one change would give a larger image?
