Properties of EM Waves: Practice Problem & Solution

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of EM Waves. Understanding the underlying formula is key to arriving at the correct answer below:

X-rays have wavelengths on the order of atomic spacings in solids. They are diffracted by the crystal lattice, making them suitable for investigating the structure of solids (X-ray crystallography).
