Answer:
resolution
Step-by-step explanation:
Resolution is the ability of the lenses in the microscope to clearly distinguish between two adjacent objects as distinct and separate.
A compound light microscope has a maximum resolution of 0.2 µm, which means it can clearly distinguish between two adjacent, but distinct objects. Any objects closer than 0.2µm will be seen as 1 object.
Have a lovely rest of your day! :)
