☛ A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright virtual images.
A concave lens is thin in the middle but thicker at the edges.
It can form both real and virtual images.
A concave lens diverges a parallel beam of light rays.
The principal focus of a concave lens is a point on its principal axis from which light rays,originally parallel to the axis,appear to diverge after passing through the concave lens.
A concave lens is also known as diverging lens because it diverges parallel beam of light rays.
A concave lens has a virtual focus.
Concave lenses are used to correct myopia which is also called nearsightedness.
concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
