Question 1:

A near-sighted person might correct his vision by wearing diverging lenses with focal length f = -50 cm. When wearing his glasses, he looks not at actual objects but at the virtual image of those objects formed by his glasses. Suppose he looks at a 12 cm long pencil held vertically 2.0 m from his glasses.

a. Use ray tracing to determine the location and height of the image. Clearly mark the object, image, object distance, image distance.

b. Show your calculations.

c. Write down the image characteristics.
