This article deals with the various properties of electromagnetic radiation, its sources and detectors, its nature, and its uses. A brief discussion on the absorption spectrum of the Earth's atmosphere and the atmospheric windows, and celestial objects seen through optical and radio telescopes is ...
To a physicist,lightmeans an energy that is anywhere along the electromagnetic spectrum, from ELF waves to gamma radiation. Visible light is only a narrow part of the spectrum that is most familiar to us because our eyes can detect it. In the Newtonian model of the universe everything is m...
The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma rays. Conversely, radio waves have much longer wavelengths, reaching anywhere from 1 mm to 100 km, depending on the frequency. The distance between repetitions in the ...
The objective of this article was to explore the electromagnetic spectrum to find imaging techniques which may deliver diagnostic information of equal, or improved, standing to conventional radiographs and to explore any developments within radiography which may yield improved diagnostic data. A ...
Wireless telephones causing Wi-Fi to drop is an example of radiated electromagnetic interference. Conducted EMIhappens when there is a physical electrical path from the source to the receptor. This is often along power transmission lines. Some sources may be a large motor or power supply. An exa...
conveys a message or information or order. For example,I signaled to my mother that the dish was very tasty. The hand gesture conveyed the message to my mother through the medium of light. Talking is another example where we pass on our thoughts to the other person through the medium of ...

So what is it?Read on to find out. (Source: NASA)What Are the Three Main Regions of the Solar Spectrum?The light energy the sun produces that reaches Earth is comprised of electromagnetic radiation of three primary types.Each type of light is part of the solar spectrum that makes up ...
, electroluminescence) of electromagnetic radiation from a sample. Optical spectrometers are concerned with electromagnetic radiation that falls within the optical region of the electromagnetic spectrum which is light spanning the ultraviolet, visible and infrared wavelength regions of the spectrum....
The biosphere is often broken down into smaller groups of related things to make it easier to understand its structure. For example, we may break it down like this: Biosphere- The biosphere contains all living things on Earth. Biome- A biome is a large collection of organisms occupying a ma...
