Electromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer.
The EM spectrum is the range of all possible frequencies of electromagnetic waves. At one end of the spectrum are the waves with the lowest frequencies. At the other end are the highest frequency waves. The spectrum is broken up into regions that define each of the different wave types.
