Which statement about a Stand magnifier is NOT true?

• A. Non-parallel light leaves the magnifier
• B. The object is located inside the primary focal point of the lens for most stand magnifiers
• C. The object to lens distance is fixed
• D. Accommodation is not required for stand magnifier

Answer: (D)

With a stand magnifier, the lens sits in a fixed position in a stand and the page is placed close to the lens, usually just inside the lens’s focal point to create a magnified virtual image. Because the object is within the focal length, the rays leaving the lens do not emerge parallel; they are diverging, forming a magnified virtual image for the eye to view. The eye still has to focus at the distance where that virtual image is seen, so some accommodation is needed to view the magnified image comfortably. That means the statement that accommodation is not required is not true. Context on the other points: the page is placed within the primary focal point to achieve magnification, so the object-to-lens distance is effectively fixed by the stand, and the light leaving the lens is not parallel in this typical setup.
