Electromagnetic spectrum - Wikipedia
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
Electromagnetic Spectrum Definition and Explanation
2023年8月29日 · What Is the Electromagnetic Spectrum? The electromagnetic spectrum is the continuous spectrum of electromagnetic radiation. It covers an enormous frequency range, from about 1 hertz (Hz) at the extreme low end to over 10 25 Hz at the high end, with no gaps in the frequency range.
