X-rays are a form of electromagnetic radiation with a shorter wavelength and higher energy than visible light. They are generated when high-energy electrons collide with matter, typically a metal target in an x-ray tube. X-rays can penetrate through many materials, including soft tissue and bone, making them useful for medical imaging and other applications.
