An x-ray is a high energy electromagnetic wave that passes through many objects. They are used in medical diagnosis to take a picture of the insides of human bodies. There are two main classifications of x-rays: soft x-rays and hard x-rays.

“Soft X-rays have comparatively high frequencies — about 3 × 1016 cycles per second, or hertz, to about 1018 Hz — and relatively short wavelengths — about 10 nanometers (nm), or 4 × 10−7 inches, to about 100 picometers (pm), or 4 × 10−8 inches…Hard X-rays have frequencies of about 1018 Hz to higher than 1020 Hz and wavelengths of about 100 pm (4 × 10−9 inches) to about 1 pm (4 × 10−11 inches).”1
