Question

State the nature of image formed by concave lens.

Hint:

Remember: A concave lens always forms a virtual, erect, and diminished image. The image is always located on the same side as the object.

Answer 1

A concave lens is a diverging lens, and the image formed by it has the following characteristics: The image formed by a concave lens is always virtual. This means that the light rays do not actually meet after passing through the lens, but only appear to diverge from a point behind the lens. A virtual image cannot be projected onto a screen. The image formed by a concave lens is upright (erect). This means that the image maintains the same orientation as the object. The rays of light appear to diverge in such a way that the image is oriented the same as the object. The image formed by a concave lens is always smaller than the object. This is because the lens causes the parallel rays of light to diverge, reducing the size of the image compared to the object. Therefore, the image is diminished. The image formed is located on the same side of the lens as the object. This is because the diverging rays appear to originate from a point behind the lens, so the image is formed on the same side as the object. No matter where the object is placed (whether near or far from the lens), a concave lens will always form a virtual, erect, and diminished image on the same side as the object.
