A near-sighted person might correct his vision by wearing diverging lenses with focal length f = -40cm . When wearing his glasses, he looks not at actual objects but at the virtual images of those objects formed by his glasses. Suppose he looks at a 10cm -long pencil held vertically 2.0m from his glasses.
A.) Use ray tracing to determine the location of the image.
B.) Use ray tracing to determine the height of the image.
