Question

X-ray electromagnetic radiation lies in the range

• A. $2.5\ \mu\text{m}$ to $25\ \mu\text{m}$
• B. $400\text{ nm}$ to $800\text{ nm}$
• C. $0.1\text{ nm}$ to $1\text{ nm}$
• D. $10\text{ nm}$ to $100\text{ nm}$

Hint:

Familiarity with the standard boundaries of the electromagnetic spectrum is critical for instrument-related questions.
X-rays have wavelengths on the order of atomic spacings ($\approx 1\text{ \AA}$ or $0.1\text{ nm}$), which is why they are ideal for crystal diffraction studies.
