Question

Resolution power of scanning electron microscope is

• A. $0.0001$nm.
• B. $0.01$nm.
• C. $0.1$nm.
• D. $5-20$nm.

Answer 1

The correct option is D $5-20$nm.

Scanning electron microscope (SEM) is one of the most widely used instrumental methods for the examination and analysis of micro- and nanoparticle imaging characterization of solid objects. One of the reasons that SEM is preferred for particle size analysis is due to its resolution of 5-20 nm.
So, the correct option is D.
