The image displays two diagrams related to optics and the human eye. The first diagram, labeled Figure 13:17, illustrates the bending of light rays as they pass through a biconvex lens, indicating refraction from a less dense to a more dense medium. Parallel light rays are shown converging at a focal point after passing through the lens. The second diagram, labeled Figure 13:18, depicts a cross-section of the human eye, illustrating the mechanisms for near and distant vision. It labels various parts of the eye, including the cornea, iris, ciliary body, suspensory ligament, and lens. The diagram shows how the shape of the lens changes for distant and near vision, with the ciliary body being relaxed for distant vision and contracted for near vision. There is also a small diagram on the right showing a pencil in a glass, illustrating the apparent position versus the real position of an object in water. The image is printed on paper. There are no people or any indication of a city, including Jauro Yinu, Nigeria. in Jauro Yinu, Nigeria
