X-Rays

X-rays are a form of electromagnetic radiation with high energy and short wavelengths. They were discovered by Wilhelm Conrad Roentgen in 1895. X-rays are invisible to the human eye and have the ability to pass through soft tissues and organs, but are absorbed by denser materials such as bones and metal. This property makes x-rays extremely useful in the field of medicine for diagnostic imaging.

Properties of X-Rays:

• Penetration: X-rays can penetrate soft tissues and are absorbed by denser materials.
• Invisibility: X-rays are invisible to the human eye.
• Ionizing: X-rays have enough energy to ionize atoms and disrupt molecular bonds.
• High energy: X-rays have higher energy than visible light.

Uses of X-Rays:

X-rays have a wide range of applications, including:

• Medical Imaging: X-rays are commonly used to create images of the inside of the body to diagnose and monitor conditions.
• Security: X-ray machines are used for security screening at airports and other high-security areas.
• Industrial Testing: X-rays are used to inspect the integrity of welds and metal components in the industrial sector.
• Research: X-rays are used in scientific research to study the structure of materials at the atomic level.
