Answer:
Resolution.
Step-by-step explanation:
This is the ability to distinguish between two separate points. if two separate points can not be seen separately, but as a single point, they can not be resolved. Consequently Resolution is the amount of details of an object that that can be seen. Thus the more the higher the resolution of an object the more the detail of the object that can be seen.
For example the maxiimum reso;ution of light microsope is 20nm. Therefore if two objects are placed together more than 20nm apart , they can not be seen(resolved); that is distinguished from one another by light microscope,This is the limImitation of light microcope.
Electron microscope makes use of beam of electrons for focusing, therefore has resolution than light microscope
