This is a photograph of an open textbook, with a diagram of a lens experiment and accompanying text. The text describes an experiment to determine the focal length of a lens using an illuminated object, a meter rule, a lens, and a white screen. The diagram illustrates the path of light rays through a convex lens, forming an image on a screen. The text further details the procedure for obtaining a sharp image by adjusting the position of the lens and screen and measuring the object and image distances. The experiment was repeated for multiple positions, and the results are to be tabulated. A page number "60" is visible at the bottom right of the page. The photograph is taken from a slightly elevated angle, showing the book lying on a patterned surface, possibly a table with a wood-grain design. There is no information in this image that provides any indication of the location being Jalingo, Nigeria.
