Focal point on converginf lens

WebConverging 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. In a converging lens light is reflected off an object and travels to a lens. Parallel light rays enter the lens and on ... WebMar 5, 2024 · The focal point is a property of the lens. It is where parallel light would converge (in practice, that is light that "appears to come from infinitely far away"). …
