The bulge of the convex lens gathers light from a wide area and “condenses” it so the image on the other side is sharp and bright. It is also upside down. The place where the image forms is called the “focal length” of the lens. The distance between the object viewed and the lens is the focal length of the object. The magnification of a lens is determined by dividing the focal length of the object by the focal length of the image. A tree that’s fifte
