Question

Measurement of grain size by using X-ray diffraction line broadening can be done by:

• A. Bragg’s Law
• B. Debye-Scherrer Formula
• C. Total Internal Reflection
• D. Moseley Law

Hint:

Grain size can be calculated by using the broadening of diffraction peaks in X-ray diffraction, and the Debye-Scherrer formula is the standard method.

Answer 1

The Correct Option is B

Step 1: Understanding the Debye-Scherrer Formula.
The Debye-Scherrer formula is used to estimate the grain size of a material by analyzing the broadening of X-ray diffraction lines.
Final Answer: \[ \boxed{\text{The correct answer is (2) Debye-Scherrer Formula.}} \]
