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.
This radiation comprises the. spectrum of energy ranging from radio waves on one end to gamma rays on the. other. It is called the electromagnetic spectrum because this radiation is associat-. ed with electric and magnetic fields that transfer energy as they travel through. space. Because humans can see it, the most familiar part of the electromagnetic. spectrum is visible lightâred, orange, yellow, green, blue, and violet.
