Question

The characteristic length scale of nanomaterials is:

• A. 1-100 nm
• B. 1-500 nm
• C. 1-200 nm
• D. 1-300 nm

Hint:

Nanomaterials typically have unique optical, electronic, and mechanical properties that arise due to their small size and high surface area.

Answer 1

The Correct Option is A

Step 1: Definition of nanomaterials.
Nanomaterials are defined as materials with structural elements in the size range of 1–100 nanometers. These materials exhibit unique properties compared to their bulk counterparts due to their small size.

Step 2: Conclusion.
Thus, the correct range for the characteristic length scale of nanomaterials is 1-100 nm.
