X-rays are:
**Core Concept**
Electromagnetic radiation in the form of X-rays is used in medical imaging to produce images of internal structures of the body. X-rays are a type of ionizing radiation that can penetrate soft tissues but is absorbed by denser materials such as bone, making them useful for visualizing skeletal structures.
**Why the Correct Answer is Right**
X-rays work by interacting with the electrons in the atoms of the materials they pass through. When X-rays hit a material, they can be absorbed, scattered, or transmitted. The amount of absorption or scattering depends on the density and atomic number of the material. Denser materials like bone absorb more X-rays, resulting in a darker image on the radiograph, while less dense materials like soft tissues allow more X-rays to pass through, resulting in a lighter image.

**Clinical Pearl / High-Yield Fact**
It's essential to note that X-rays have a relatively low penetration and can be affected by various factors such as the energy level of the X-rays, the thickness of the material, and the angle of incidence. This is why X-ray images may not always provide a clear picture of internal structures, and other imaging modalities like CT scans or MRI may be necessary for more detailed visualization.
