Which statement best matches electronic magnification?

• A. Magnification is accomplished through the use of electronic equipment.
• B. The object is physically enlarged.
• C. The enlargement is based on the object being moved closer to the observer.
• D. The size of the object at a given location is increased through optical principles.

Answer: (A)

Electronic magnification relies on imaging the object with an electronic sensor and displaying an enlarged version on a screen or monitor. The object itself stays the same size; what changes is how large the image appears because the display and processing magnify it electronically. This distinguishes it from physically enlarging the object, or from moving the object closer to increase apparent size (which uses distance or angular size), or from optical magnification that relies on lenses to bend light. So the best-fit description is that magnification is achieved through electronic equipment.
