How far does the light ray travel inside the glass beforeemerging on the far side?
3. A near-sighted person might correct his vision by wearingdiverging lenses with focal length f = -60 cm . Whenwearing his glasses, he looks not at actual objects but at thevirtual images of those objects formed by his glasses. Suppose helooks at a 10 cm -long pencil held vertically 1.8 m from hisglasses.
A. Use ray tracing to determine the location of the image.
B. Use ray tracing to determine the height of the image.
