Optics

A convex lens is a lens that is curved outward ( convex): the ends are narrow and the middle is wide. Often referred to as a converging lens. Light passing through a convex lens is converged to a point. This point is also called a focal point.

Compare: concave lens.

ConvexIn mathematics, an object is convex if for any pair of points within the object, any point on the straight line segment that joins them is also within the object. For example, a solid cube is convex, but anything that is hollow or has a dent in it is notConvex hullIn mathematics, the convex hull for an object or a set of objects is the minimal convex set containing the given objects. It is the minimal convex set because the convex hull is a subset of any convex set which contains the given objects. The convex hullConvex ComputerConvex Computer was a computer company that produced a number of minisupercomputers, supercomputers for small to medium-sized businesses. Their later Exemplar series of parallel computing machines was based on the Hewlett-Packard PA-RISC CPU series, and i

It is called a convex combination since all possible convex combinations (given the base vectors) will be paConvex and ConcaveConvex and Concave is a lithograph print by the Dutch artist M. Escher which was first printed in March, 1955. It depicts an ornate architectural structure with many stairs, pillars and other shapes. The relative aspects of the objects in the image are di
