electromagnetic spectrum

noun

1. the entire spectrum, considered as a continuum, of all kinds of electric, magnetic, and visible radiation, from gamma rays having a wavelength of 0.001 angstrom to long waves having a wavelength of more than 1 million km.

electromagnetic spectrum

noun

1. the complete range of electromagnetic radiation from the longest radio waves (wavelength 10 ⁵metres) to the shortest gamma radiation (wavelength 10 ^–13metre)

electromagnetic spectrum

1. The entire range of electromagnetic radiation. At one end of the spectrum are gamma rays, which have the shortest wavelengths and high frequencies. At the other end are radio waves, which have the longest wavelengths and low frequencies. Visible light is near the center of the spectrum.

electromagnetic spectrum

1. The family of electromagnetic waves . The electromagnetic spectrum, starting from the waves with the longest wavelengths (and least energy ), consists of radio waves , microwaves , infrared radiation , visible light , ultraviolet radiation , x-rays , and gamma radiation . Members of the family differ from one another only in their wavelength, or frequency . For example, the wavelength of blue light is roughly half that of red light, but the waves corresponding to the two colors are otherwise identical.

First recorded in 1935–40

Example Sentences

But unlike any other known pulsar, Medvedev said the Crab Pulsar features a zebra pattern -- unusual band spacing in the electromagnetic spectrum proportional to band frequencies, and other weird features like high polarization and stability.

From Science Daily

Many objects in space, including distant galaxies and planets, emit light on the electromagnetic spectrum.

From BBC

This frequency range is equivalent to the electromagnetic spectrum used in astronomical observations and includes a large portion that has never been explored in the detection of GWs before.

From Science Daily

The light from the earliest galaxies is stretched from ultraviolet and visible wavelengths into the infrared - the part of the electromagnetic spectrum to which James Webb's mirrors and instruments were specifically tuned.

From BBC

Now, Penn Engineers have developed a new tool that could prevent such problems from ever happening again: an adjustable filter that can successfully prevent interference, even in higher-frequency bands of the electromagnetic spectrum.
