The images formed by concave lenses are always real are always virtual. ... Show transcribed image text. could be real or virtual; it depends on whether the object distance is smaller or greater than the focal length could be real or virtual, but always real when the object is placed at the focal point.

Explanation:
A concave lens is a lens that is thinner at the center and thicker at the edges. When light passes through a concave lens, it is diverged or spread out. This divergence of light causes the image formed by a concave lens to have certain characteristics.

Virtual image formation:
When light rays diverge after passing through a concave lens, they appear to come from a point behind the lens. This point is called the virtual image. The virtual image formed by a concave lens is always upright and cannot be projected onto a screen. It can only be seen when looking through the lens.

Reasons behind virtual image formation:
The formation of a virtual image by a concave lens can be explained by the way the lens bends light rays. The lens is thicker at the edges, causing light rays passing through the edges to be refracted or bent more than those passing through the center. This bending of light rays causes them to diverge or spread out, resulting in the formation of a virtual image.

Characteristics of a virtual image formed by a concave lens:
1. Upright: The virtual image formed by a concave lens is always upright, meaning it has the same orientation as the object.
2. Reduced in size: The virtual image formed by a concave lens is smaller in size compared to the object.
3. Cannot be projected: The virtual image formed by a concave lens cannot be projected onto a screen or surface. It can only be seen when looking through the lens.

Conclusion:
In summary, a concave lens always forms a virtual image. This image is upright, reduced in size, and cannot be projected onto a screen. The divergence of light rays after passing through a concave lens is responsible for the formation of a virtual image.

Because the lights rays that emerge from a concave lens gets diverged ...... they don't meet actually ,instead they appear to meet
