State two applications of x-rays

Explanation

### Step-by-Step Text Solution

1. **Introduction to X-rays**: X-rays are a form of electromagnetic radiation that have a wavelength shorter than visible light. They are widely used in various fields due to their ability to penetrate materials and provide images of internal structures.

2. **Application in Medical Field**: One of the primary applications of X-rays is in the medical field. X-rays are commonly used for diagnostic imaging, particularly to view the internal structure of bones. When a patient has a suspected fracture, an X-ray can be taken to visualize the bone and confirm the diagnosis.

3. **Application in Research**: X-rays are also extensively used in research settings. They are employed in various scientific studies, including crystallography, where X-ray diffraction is used to determine the atomic and molecular structure of a crystal. This helps in understanding the arrangement of atoms in materials.
