WebbSince Illustrator CS5, these lens-shaped objects can be created in a ridiculously simple and quick way by modifying a thick stroke using the Width tool. This also has the advantage of keeping the result editable. Draw a path and give it an adequate stroke width (e.g. 10 pt), which will make for the base 'rectangle'.

WebbDefinition of Concave Mirror. Concave mirrors are converging mirrors. The parallel incident rays fall on the mirror’s surface and the rays reflect and meet at a certain point known as the focal point. A concave mirror’s shape is similar to a spoon. When we place this mirror too close to an object, we get a magnified and virtual image. WebbA concave lens is a piece of transparent material that has two curved surfaces and that is thinner in the middle and thicker at the edge. The lenses shown in choices A and B have straight sides, so it cannot be either of them. The lens shown in choice C has two curved sides, but it is thicker in the middle and thinner at the edge.
