The principal rays are drawn as you click-drag the top of the arrow shaped object in the animation.  Which statement is true?  Start

The image of an object that is not on the principal axis can never overlap the object. - Correct!
The magnification changes sign when the tip of the arrow is dragged below the principal axis.
Light rays leaving the tip of the arrow always pass through the image.
Virtual images always invert the object.
