If the object is placed between infinity and optical centre O of the concave lens, how will the image be formed after refraction?

Correct option is B

The correct answer is (b) Virtual and erect.
· When an object is placed anywhere between infinity and the optical center O of a concave lens, the image formed after refraction will be virtual, erect, and diminished.
· A concave lens always forms a virtual image, meaning the image cannot be projected on a screen.
· The image is also smaller than the object and appears on the same side of the lens as the object.
· The concave lens diverges light rays, making the image appear as if it is coming from a point between the optical center and the focal point on the same side as the object.
Additional Knowledge:
· Real and inverted: Concave lenses do not form real and inverted images; only convex lenses do in certain conditions.
· Real and enlarged: This applies to convex lenses in specific positions, not concave lenses.
· Real and same size: This option is incorrect for concave lenses, as they do not form real images of the same size.
