Chose whether the following statement is true or false.

An image formed by a concave lens is always virtual.

The given statement is true.

• A concave lens is a diverging lens i.e. when a beam of parallel rays is incident on a concave lens, the rays diverge in different directions.
• Due to this, refracted rays from a concave lens never meet to form an image. 
• Rays just appear to come from a point.
• And virtual images are formed when rays appear to come from a point.

Therefore, we can conclude that a concave lens always forms a virtual image.
