A near-sighted person might correct his vision by wearing diverging lenses with focal length f = -60cm. 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 1.6m 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?
