Three objects are located 7.5 cm (object 1), 10.0 cm (object 2) and 15.0 cm (object 3) to the left of a converging lens whose focal length is 5.0 cm. The objects' heights are the same as their distances to the lens.
(a) Draw a ray diagram to scale (or to a half-size reduced scale) to determine each of the image distance and magnification of each object through the lens.
(b) Use the thin lens and magnification equations to verify your answers from part (a).
