Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.
The most common type of spectrometer, the USB spectrometer, measures the properties of light over a defined range of the electromagnetic spectrum. The spectral range measured varies from device to device depending on the design of the spectrometer and its intended use, but most operate around the...
(BaF2) is transparent to a broad region of theelectromagnetic spectrumand is used to make opticallensesand windows forinfraredspectroscopy. Theoxygencompoundbarium peroxide (BaO2) was used in the 19th century for oxygen production (the Brin process) and as a source ofhydrogen peroxide. Volatile ...
using spectral data from samples to determine their chemical properties. Most molecules absorb light in the IR region of the electromagnetic spectrum, converting it to molecular vibration, and this absorption characterises the nature of the chemical bonds contained in a sample. In IR imaging,...

This article considers additional kinds of information that can be obtained by using imagery obtained in the thermal infrared and radar bands of the electromagnetic spectrum, in conjunction with conventional aerial photography.doi:10.1016/0031-8663(66)90014-7David M. Carneggie...
Infrared light is on the IR spectrum, which is the section of the electromagnetic spectrum that lies between visible red light and microwaves (see Figure 1). Figure 1: The Electromagnetic Spectrum. The peaks of an IR spectrum fingerprint are very useful for identifying the functional groups (...
(a picometer is one-trillionth of a meter). These electromagnetic waves occupy the same region of the EM spectrum as gamma-rays. The only difference between them is their source: X-rays are produced by accelerating electrons, whereasgamma-rays are produced by atomic nucleiin one of four ...
X-Rays are forms of electromagnetic radiation. One property of X-Ray is that they are capable of travelling in the vacuum. Visit to learn more about X-Rays properties, wavelength, uses, working and its invention.
