Which option correctly describes the image formed by a double concave lens?

• A. Magnified, real image
• B. Reduced, upright, virtual image
• C. Inverted, real image
• D. Inverted, reduced, virtual image

Answer: (B)

A double concave lens, also known as a diverging lens, always produces images that are virtual, upright, and reduced in size. This characteristic is due to the way light rays interact with the lens. When parallel light rays pass through a double concave lens, they diverge or spread out. The rays appear to originate from a point on the same side of the lens as the object, which leads to the formation of a virtual image. This image is virtual because it cannot be projected onto a screen; it only seems to exist where the light rays appear to come from. Additionally, because the image is produced by diverging rays, it is upright relative to the object and smaller than the actual object, resulting in a reduced size. The other choices indicate conditions (like being real, inverted, or magnified) that do not apply to images formed by a double concave lens, which consistently yields virtual, upright, and reduced images.
