This figure is a schematic diagram of an optical experiment on the focusing effect of a magnifying glass. Based on the refraction direction, lenses are of two types, concave and convex lens. Convex lenses have a thicker middle part when compared to their edges. When parallel light rays pass through the convex lens, they are converged to meet at a point named principal focus.
