When EM radiation interacts with single atoms and molecules, its behavior also depends on the amount of energy per quantum (photon) it carries. Spectroscopy can detect a much wider region of the EM spectrum than the visible wavelength range of 400 nm to 700 nm in a vacuum. See more The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The … See more Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength See more Radio waves Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators.
