Prior to the development of the digital camera, the 35-mm film camera was the norm. The designation "35 mm" refers to the size of the film (screen) on which the image is formed. Suppose you wish to use one of these cameras to photograph a 19-m-tall tree that is 47 m away and have the tree's image fill the entire 35-mm film. What must the focal length of the camera lens be?
