What is a common application of a converging lens?

A converging lens, also known as a convex lens, is primarily used for projecting images because it has the ability to focus light rays that are parallel to its axis. When light passes through a converging lens, it refracts inward and converges at a focal point. This property makes it suitable for applications such as cameras, magnifying glasses, and projectors, where a clear image is required. The curvature of the lens determines the degree of convergence and thus the quality of the image produced.

In contrast, the other options do not align with the primary functions of a converging lens. Creating shadows is more related to opaque objects blocking light rather than the focusing capabilities of a lens. Scattering light is typically a characteristic of lenses that are not designed to converge light effectively, such as a diverging lens. Absorbing radiation is also irrelevant to the function of a converging lens, as this describes materials that take in energy rather than focusing it. Therefore, projecting images directly illustrates the essential function of a converging lens.
