Focal point of the lens
WebThe lens should form the image at the far point. When glasses (or contact lenses) are used to correct farsightedness, where should the corrective lens form an image of an object … WebA lens’s focal point is the point at which light rays meet after reflection or refraction. Converging lenses have a focal point on the side of the lens opposite of where the object is placed; therefore, converging lenses have a positive focal length. A converging lens is thicker in the middle than it is at the ends.
