a) The apparent increase in the size of an image. Magnification
b) Ability to be distinguished from the surroundings. Contrast
c) The ability to distinguish between two separate structures that are very close to one another. Resolution
Microscopes are used to study very small features in nature. They have unique parts that helps to see very minute details in the field of view.
