B) greatest at high power and decreases as magnification increases
C) greatest at scanning power and decreases as magnification increases
D) greatest at low power and increases as magnification increases

Question

Quizplus · Accepted Answer

Depth of field refers to the range of distance that appears acceptably sharp in an image. At lower magnifications (such as scanning power), there is a larger depth of field, meaning more of the image will appear acceptably sharp. As magnification increases, depth of field decreases, meaning less of the image will appear acceptably sharp. So, the greatest depth of field is actually at the lower magnifications, such as scanning power.
