The table summarizes the three types of images formed by single thin lenses. These are referred to as case 1, 2, and 3 images. Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3).
The magnification is also less than 1, meaning the image is smaller than the object—in this case, a little over half its size. The image distance is negative, meaning the image is on the same side of the lens as the object.
Illustrate the formation of images using the technique of ray tracing. Determine power of a lens given the focal length. Lenses are found in a huge array of optical instruments, ranging from a simple magnifying glass to the eye to a camera’s zoom lens.

A digital image is made up of rows and columns of pixels. A pixel in such an image can be specified by saying which column and which row contains it. In terms of coordinates, a pixel can be identified by a pair of integers giving the column number and the row number.
The optical imaging of light incident at the cornea into an image at the retinal photoreceptors is the first visual transformation. Since all of our visual experiences are influenced by this transformation, we begin the study of vision by analyzing the properties of image formation.
