Question

Quizplus · Accepted Answer

The focal plane thickness refers to the depth of field, which is the area in which objects will appear in focus in an image. As magnification increases, the depth of field decreases, meaning that objects in front of or behind the subject will become more blurred. Therefore, the focal plane thickness (depth of field) decreases as magnification increases, leading to a narrower in-focus area.
