Text Solution

Verified by Experts
The correct answer is:
A
X-rays have wavelengths in the range of approximately 0.01 to 10 nanometers (1 Å = 10^{-10} m). To study crystal structures effectively, the wavelength of X-rays needs to be on the order of atomic dimensions, typically around 1 Å. Therefore, the suitable range for X-rays to study crystal structures effectively is from about 0.1 Å to 2 Å.
Hence, the correct option is A.
