Answer:
The correct answer will be-the field of view will decrease.
Step-by-step explanation:
Magnification of a microscope is the amount of visual enlargement of an object placed in a microscope which is usually measured in the multiples like 2x, 4x and 10x and so on. The filed of view is the observable area a person can observe through any optical device with his eyes.
The magnification and field of view show the inversely proportional relationship between them. As the magnification increases, the field of view decreases that is filed of view will be larger at 2x compared to 400x.
Thus, the field of view will decrease is the correct answer.
