X-rays

An X-ray is a form of high-energy electromagnetic radiation that has the ability to penetrate through matter.

Wavelengths

They have a wavelength that ranges from 10 picometers to 10 nanometers, corresponding to frequencies between 30 petahertz to 30 exahertz and energies between 145 eV to 124 keV. X-rays have a shorter wavelength compared to UV rays, and a longer wavelength than gamma rays.

History

X-ray radiation was discovered by the German scientist Wilhelm Conrad Röntgen in 1895. He named it X-ray to indicate that it was an unknown form of radiation.

Spelling

The spelling of X-ray in English can vary such as x-ray, xray, or X ray.

Uses

The most common use of X-rays is to check for bone fractures, but they can also be used to detect other medical conditions such as pneumonia through chest X-rays and breast cancer through mammograms.
