Concave lens

Answer: A Concave lens always produce a virtual and diminished image.

Answer 2

Answer:

A biconcave lens will always give a virtual, erect and diminished image.

Explanation:

Biconcave lens:

• We know that a concave lens is one that has at least one surface that slopes inwards.

• It is classified as a diverging lens because it spreads out light beams that have been refracted through it.

• Concave lenses are thinner in the middle than at the edges and are used to correct short-sightedness.

• Because of this impact, it is also referred to as a negative lens or a diverging lens.

• A concave lens' image is always diminished (very tiny), virtual, and erect, which means it appears to be farther away than it actually is, and thus smaller than the object itself.

So, biconcave lens will always give a virtual, erect and diminished image.
