AI overview

X-rays are a form of radiation that can pass through solid objects, allowing us to see inside things like the human body or other materials without cutting them open. This ability to visualize hidden structures makes X-rays valuable for medical diagnosis and many other practical applications.

An X-ray is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 nanometers to 10 picometers, corresponding to frequencies in the range of 30 petahertz to 30 exahertz ( to ) and photon energies in the range of 100 eV to 100 keV, respectively.
