WebUsing a positive lens of focal length f, a virtual image results when S 1 < f, the lens thus being used as a magnifying glass (rather than if S 1 >> f as for a camera). Using a negative lens (f < 0) with a real object (S 1 > 0) can only produce a virtual image (S 2 < 0), according to the above formula. WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. However, these conventions are arbitrary, and physicists could just as easily have made the signs opposite. Thin lens rules and sign conventions
