A convex lens forms a real, inverted and diminished image. The position of the object is:

Correct option is D

Sol: The correct answer is (d) Beyond 2F

Key Points:

1. Real and inverted image: The object must be placed beyond the focal point (F) of the lens.
2. Diminished image: This happens when the object is placed beyond 2F, meaning farther from the lens than twice the focal length.

• A. At infinity: If the object is at infinity, the lens forms a real, inverted, and highly diminished point image at the focal plane (F). This is not consistent with the generic case of a diminished image.
• B. Between O and F (optical center and focal point): In this case, the image is virtual, erect, and magnified. This contradicts the conditions given.
• C. Between F and 2F (focal point and twice the focal length): Here, the image formed is real, inverted, and magnified. This also does not match the conditions.
• D. Beyond 2F: When the object is placed beyond 2F, the lens forms a real, inverted, and diminished image, located between F and 2F.
