electromagnetic spectrum An electromagnetic spectrum is defined as the entire range of electromagnetic waves from low to high frequency. An example of an electromagnetic spectrum is the low frequency radio to the high frequency gamma ray waves. the complete range of frequencies of electromagnetic waves from the lowest to the highest, including, in order, radio, infrared, visible light, ultraviolet, X-ray, and gamma ray waves.

The Nature of Light The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The electromagnetic spectrum of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. discussion of the regions (or bands or types) of the electromagnetic spectrum is given below. Note that there are no precisely defined boundaries between the bands of the electromagnetic spectrum; rather they fade into each other like the bands in a rainbow (which is the sub-spectrum of visible light).

The Electromagnetic Spectrum 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.he other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. You know more about the electromagnetic spectrum than you may think.

- A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary infinitely within a continuum.The word was first used scientifically within the field of optics to describe the rainbow of colors in visible light when separated using a prism.lectromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer.

What Is EMF? The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the scientific name for types of photon radiation. Electromagnetic radiation consists of photons (light particles) that travel in a wave-like pattern at the speed of light. The amount of energy found in these photons forms the various types of electromagnetic radiation in the spectrum, which is expressed in terms of energy, wavelength or frequency.

Electromagnetic pulse An electromagnetic pulse is a short burst of electromagnetic energy. Its short duration means that it will be spread over a range of frequencies. Pulses are typically characterized by: The type of energy (radiated, electric, magnetic or conducted). The range or spectrum of frequencies present.

The Electromagnetic Spectrum Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light. Each photon contains a certain amount of energy. The different types of radiation are defined by the the amount of energy found in the photons.

Visible spectrum The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz. The spectrum does not, however, contain all the colors that the human eyes and brain can distinguish. Unsaturated colors such as pink, or ...

- As such, it is a part of electromagnetic spectrum, which encompasses the entire range of electromagnetic radiation, from its lowest to its highest frequencies. The EM spectrum is, somewhat arbitrarily, divided into a number of sub-ranges. Following table shows the electromagnetic spectrum, with some of the main sources of electromagnetic pollution.

- There are different kinds of electromagnetic waves and all of them have different wavelengths, properties, frequencies and power, and all interact with matter differently. The entire wave system from the lowest frequency to the highest frequency is known as the electromagnetic spectrum. The shorter the wavelength, the higher its frequency and vice versa. White light, for example, is a form of radiant energy, and its frequency forms a tiny bit of the entire electromagnetic spectrum.
