Image Formation in Magnifying Glass Setup

Steps:

• A converging lens acts as a magnifying glass when the object is placed inside its focal length.
• Rays from the object diverge after passing through the lens.
• The image forms on the same side as the object by extending rays backward.
• This results in a virtual, upright, and enlarged image.

Why D is correct:

• For a converging lens, when object distance $u < f$ (focal length), the lens formula $\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$ gives negative $v$, indicating a virtual image on the object side, which is upright.

Why the others are wrong:

• A: Real images from converging lenses are inverted, not upright.
• B: Real and inverted images form only when the object is beyond the focal length.
• C: Virtual images from converging lenses are upright, not inverted.

Final answer: D
