Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Scanning Electron Microscopy (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
Step 2: Meaning
It is widely used to study the morphology, topography, and composition of materials at the nanoscale.
Step 3: Analysis
- SEM provides high-resolution images that allow for the direct measurement and determination of particle size and shape. - FTIR and UV-Vis are spectroscopic techniques used for identifying functional groups and electronic transitions, respectively.
Step 4: Conclusion
Hence, SEM is the correct instrument for particle size determination. Final Answer: (A)
