A burning glass is used to concentrate sunlight in a tiny spot, and it works by using a converging lens to refract the sunlight and focus it onto a small point. A converging lens has a convex shape, and it is thicker in the middle than at the edges. When light passes through a converging lens, it bends inward toward the center of the lens, and this causes the light to converge at a focal point. This is the same principle that is used in a magnifying glass, which is another example of a converging lens.
