A concave lens refers to a lens, which exhibits at least one surface that bends inwardly. It is a diverging lens, which signifies that it disperses out the light rays that have been refracted via it. A concave lens is thinner at its midpoint in comparison to its edges and has an application in correcting short-sightedness.
The formation of an image by a concave lens is virtual, which signifies that it will seem to be farther away than it actually is, and thus, smaller in comparison to the object itself.
A concave lens is thin in the middle and thick at the edges, such that it seems to cave inwards. It spreads light rays apart producing an image smaller than the actual object.
<em><u>Images formed by a concave lens are virtual, upright, reduced in size and located on the same side of the lens as the object. Diverging lenses or concave lens always produce images that share these characteristics. The location of the object does not affect the characteristics of the image. </u></em>
