A magnifying glass is a convex lens, usually mounted in a frame with a handle, which is used to produce a magnified image of an object. The glass works by creating a magnified virtual image of an object behind the lens. However, the distance between the lens and the object must be shorter than the focal length for the glass to work. If the distance is not correct then the image will appear small and inverted. Many magnifying glasses are mounted on a stand to insure the proper distance...

Parabolic Mirror -- A parabolic reflector or parabolic dish is a reflective device formed in the shape of a paraboloid of revolution. Parabolic reflectors can either collect or distribute energy such as light, sound, or radio waves. The parabolic reflector functions due to the geometric properties of the paraboloid shape: if the angle of incidence to the inner surface of the collector equals the angle of reflection, then any incoming ray that is parallel to the axis of the dish will be...
