X-rays are a form of electromagnetic radiation, similar to visible light but with much higher energy. They can pass through most objects, including the human body, which makes them useful for medical imaging. When X-rays are directed at a body, they create images of bones and internal organs by capturing the varying levels of radiation that pass through different tissues. In medicine, X-rays help doctors diagnose conditions such as fractures, infections, and tumors. The images produced are called radiographs, and they allow healthcare professionals to see inside the body without needing invasive procedures.
