Aug 29, 2023 · 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.
Electromagnetic Spectrum - Introduction - Imagine the Universe!
Nov 14, 2014 · The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

Jun 3, 2024 · The electromagnetic spectrum is a range of all types of electromagnetic radiation, organized by wavelength. Its functions include transmitting information (like radio waves), heating (like microwaves), and imaging (like X-rays).
Electromagnetic radiation - Spectrum, Wavelengths, Properties
Dec 24, 2024 · Electromagnetic radiation is, classically speaking, a wave of electric and magnetic fields propagating at the speed of light c through empty space. In this wave the electric and magnetic fields change their magnitude and direction each second. This rate of change is the frequency ν measured in cycles per second—namely, in hertz.
