Solution

Answer

The statement is False.

Concave lenses, also known as diverging lenses, exclusively produce virtual images regardless of the position of the object. When an object is placed in front of a concave lens, the light rays diverge after passing through the lens. The virtual image formed is upright and located on the same side as the object.

In contrast to convex (or converging) lenses, which can produce both real and virtual images depending on the object's distance from the lens, concave lenses do not have the capability to generate real images. The nature of concave lenses means they always cause light rays to spread out, thus creating only virtual images that cannot be projected onto a screen.

Real images, on the other hand, can be formed by convex lenses when the object is placed beyond the focal point, resulting in a converging effect that allows the light rays to meet at a point.

In summary, since concave lenses only produce virtual images, the assertion that they can produce both real and virtual images is incorrect.
