- They are propagated in straight lines with the velocity of light.
- X-rays have a high penetrating power.
- Photographic film is blackened by X-rays.
- Fluorescent materials glow when X-rays are directed at them.
- Photoelectric emission can be produced by X-rays.
- Ionization of a gas results when an X-ray beam is passed through it.
- X rays kill the diseased tissue of the body. Hence they are used to cure intractable skin diseases, malignant tumors etc.
- Because of high penetrating power they are used to investigate the structure of metals, and gas pockets causes of weakness in structure and to detect cracks and below holes in metal plates.
