Question
In the simple magnifier example, if the image is formed at the observer's near point, 25 cm in front of her eye, what does this imply about the image distance (v) using standard sign conventions for lenses?
Correct Answer
Option B is the correct answer.
Detailed Explanation
For a simple magnifier, the image formed at the observer's near point is a virtual image, appearing on the same side of the lens as the object. By standard sign conventions, virtual images formed on the object side have a negative image distance, hence v = -25 cm.
Hint
Recall the nature of images formed by a simple magnifier and the sign conventions for virtual images.
