参考答案:
Ray 1 leaves the top of the object and is drawn such that it is parallel to the axis; therefore it emerges from the lens along a line through the focal point on the back side of the lens.
Ray 2 leaves the top of the object and is made to pass through the other focal point; therefore it emerges from the lens parallel to the axis.
Ray 3 leaves the top of the object and is directed toward the very center of the lens; therefore it emerges from the lens a the same angle as it entered.
