Quiz: What Do You Know About Thin Converging Lens? Trivia Questions - Quiz

What Do You Know About Thin Converging Lens? Thin lenses can be diverging or converging. The converging lenses are thicker in the middle than near the edges and as two focal points, located on the optical axis, a distance 'f' from the center of the lens on either side of the lens. Take up this test and get to see how much you know.
