In a concave-lens diagram of a plastic bottle, which statement is true about the image size?

• A. The actual bottle should appear larger than the image of the bottle.
• B. The image of the bottle should be upside down compared to the actual bottle.
• C. The image of the bottle should appear larger than the actual bottle.
• D. The actual bottle should be upside down compared to the image of the bottle.

Answer: (A)

A concave (diverging) lens always produces a virtual, upright, and smaller image for any real object. This means the image formed is diminished in size relative to the object, and it sits on the same side of the lens as the object rather than being inverted. Therefore, the actual bottle should appear larger than its image—the image is smaller. The image being upright rules out the option that says it would be upside down, and the image being larger would contradict the typical behavior of a concave lens, so those choices don’t fit.
