X-Rays on the EMS X-Rays have tiny wavelengths and have very high energies and frequencies. They are on the opposite end of the EM spectrum from radio waves.
how X-radiation can be used to produce an internal image of the body
X-ray beam passes through the body. As it goes through the body parts of energy of the X-ray beam are absorbed. That process is called attenuation of the X-ray beam.
