The image shows a page from a textbook with an experiment titled "EXPERIMENT 102: FOCAL LENGTH OF LENS". The experiment aims to determine the focal length of a lens using the displacement method. The apparatus required includes a lens, object, lens holder, optical bench, lamp box, and a screen. A diagram illustrates the experimental setup, showing a lens, an object (labeled 'O'), incident rays, refracted rays, and a screen where an image is formed. The diagram also labels distances related to object and image positions (U, V) and a distance 'd'. The theory section explains the relationship between object distance (u), image distance (v), and focal length (f) using the lens formula: 1/u + 1/v = 1/f. It also defines magnification (m) as the ratio of image height to object height, or image distance to object distance: m = I/OB = v/u. The procedure section begins with the first step: "Find the approximate focal length of the lens by focusing a sharp image of a distant object on a sheet of paper on the wall." The page number is clearly visible as "35". There is no information about the location of Jauro Yinu, Nigeria, in this image. in Jauro Yinu, Nigeria
