The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The `electromagnetic spectrum` of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. The electromagnetic spectrum extends from below the low.....

The electromagnetic spectrum covers a wide range of wavelengths and Photon energies. It ranges from Gamma Rays at one end (High Frequency, High Energy and Low Wave Length) to radio waves at the other (Low Frequency, Low Energy and Long Wave Length).For Ionising Radiation protection purposes we are concerned with X-Rays and Gamma Rays.
