The crystal structure can be studied by using

Options

A. UV rays
B. X-rays
C. IR radiation
D. Microwaves

Explanation

To solve the question regarding how the crystal structure can be studied, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Crystal Structure**:
- Crystal structures refer to the ordered arrangement of atoms in a crystalline material. Different types of crystals have unique arrangements that can be analyzed to understand their properties.

2. **Role of Electromagnetic Waves**:
- Electromagnetic waves encompass a range of wavelengths, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type can interact with matter in different ways.

3. **X-rays and Their Properties**:
- Among the electromagnetic waves, X-rays have specific properties that make them particularly useful for studying crystal structures. They can penetrate materials and interact with the electrons in atoms.

4. **Diffraction of X-rays**:
- One of the key properties of X-rays is their ability to produce diffraction patterns when they interact with a crystal lattice. This diffraction occurs due to the wave nature of X-rays, allowing us to observe how they scatter when they hit the crystal.

5. **Determining Crystal Structure**:
- By analyzing the diffraction patterns produced when X-rays are directed at a crystal, scientists can deduce the arrangement of atoms within the crystal. This is a fundamental technique known as X-ray crystallography.

6. **Conclusion**:
- Therefore, the correct answer to the question is that the crystal structure can be studied using X-rays, due to their unique diffraction properties.

### Final Answer:
The crystal structure can be studied by using **X-rays**.
