Mirrors and Lenses - Homework For the lenses and mirrors below, draw the lines that travel through the lens (the first two) and the rays reflected by the two mirrors. Label the focal point (F) and draw in the focal length and label it. Circle either converging or diverging and whether it forms a real or virtual image for each diagram and is concave or convex. principal axis converging/diverging real/virtual concave/convex principal axis converging/diverging real/virtual concave/convex principal axis converging/diverging real/virtual concave/convex principal axis converging/diverging real/virtual concave/convex Draw three light rays entering and leaving the lenses below showing the focal point (F) and the focal length
