electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.

Learn what the electromagnetic spectrum is and how it covers a wide range of frequencies and wavelengths of electromagnetic radiation. Find out the properties, uses, and examples of each class of electromagnetic wave, from radio to gamma rays.

Learn about the range of all types of electromagnetic radiation, from radio waves to gamma rays, and how they are measured and detected. Find out why astronomers use different units and why they put telescopes in orbit.

Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light.

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).

Learn about the electromagnetic spectrum, the range of all types of electromagnetic radiation, and its significance, applications and formulas. See the diagram of the spectrum and the examples of different types of waves, such as radio, microwave, infrared, visible, ultraviolet, X-ray and gamma-ray.

The electromagnetic spectrum consists of a group of radiations that all travel at the speed of light (\ (3\times 10^ {8},m\,s^ {-1}\)). In the middle of the EM spectrum is the visible...

The electromagnetic spectrum, or EM spectrum, is the name given to the collection of all electromagnetic radiation in the universe.

Learn about the different types of light, or electromagnetic radiation, that human eyes can and cannot see. Find out how astronomers use various wavelengths of light to study the universe and its objects.
