What image does a concave mirror form?

What image does a concave mirror form?

• A. Closer than it is
• B. Larger and closer
• C. Upright and reduced
• D. Distant and diminished

Answer: (A)

A concave mirror can form real, inverted images whose size and location depend on where the object is placed relative to the focal point. If the object is beyond the center of curvature (farther from the mirror than 2f), the image forms between the focal point and the center of curvature. In this region, the image distance is smaller than the object distance, so the image appears closer to the mirror than the object is. It’s real and inverted and usually smaller than the object. That’s why “closer than it is” fits as the best description among the options. The other statements don’t generally apply: a real image on a concave mirror is not upright and reduced in that setup, and while very distant objects can produce a small image, the image doesn’t end up distant from the mirror in the common case described by this option.
