Lenses can indeed magnify images, particularly convex lenses, which are designed to converge light rays and create a larger image. Unlike mirrors, which can also magnify, lenses achieve this effect through their curvature and refractive properties. Magnifying glasses are a common example of convex lenses used for this purpose. Concave lenses, on the other hand, do not magnify images; instead, they diverge light rays. Understanding the differences between these types of lenses is essential for applications in optics.
