Question

Quizplus · Accepted Answer

The angular magnification of a magnifying glass is largest when the image is at the near point of the eye. This is because the magnification is defined as the angle subtended by the image when at the near point divided by the angle subtended by the object at the near point. When the image is at the near point, this ratio is maximized, allowing for the greatest magnification.
