설명
Concave mirror: A concave mirror can produce a real image when the object is placed outside the focal point. While, Convex mirror: a convex mirror always produces virtual images.
Diverging lens: A diverging lens (concave lens) always produces virtual images. While, Converging lens: a converging lens (convex lens) can produce a real image when the object is placed outside the focal point.
