参考答案: To make a sharp image of an
object that is very far away, the film of a camera must be placed at the focal
length of the lens. Objects that are
very far away have light rays coming into the camera that are basically
parallel and these rays will be bent and focused to create an image at the
focal point of the lens, which is where the film should be in order to record a
focused image.
