As a gift for your birthday you receive a new lens for your 35 mm camera. (We are presuming that you previously were given a 35 mm camera that uses film because you wanted to get into photography and one of your parents had such a camera around the house. Eventually you will get a digital camera, but for the moment you are happy to settle for film on the non-automatic camera so you can really learn how the camera works, understand light levels, etc.) The lens is a lens that is good for portraits (so you can take pictures of people) and has a focal length of 105 mm. If the object (your niece) is located 4 meters in front of the lens and is 3 feet tall,

(a) How far behind the lens is the image and

(b) How big is the image that will appear on the film or digital chip?
