Apinhole camera is just a rectangular box with a tiny hole in one face. the film is on the face opposite this hole, and that is where the image is formed. the camera forms an image without a lens. (a) make a clear ray diagram to show how a pinhole camera can form an image on the film without using a lens. (hint: put an object outside the hole, and then draw rays passing through the hole to the opposite side of the box.) (b) a certain pinhole camera is a box that is 25 cm square and 20.0 cm deep, with the hole in the middle of one of the 25 cm x 25 cm faces. if this camera is used to photograph a canada goose that is 18 cm high and 1.5 m in front of the camera, how large is the image of this bird on the film? what is the lateral magnification of this camera?
