  2. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    Environment portal. Ecology portal. v. t. e. Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than 10 eV energy to ionize atoms or break chemical bonds. [1] Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ...

  3. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    The absorption of electromagnetic radiation by water depends on the state of the water. The absorption in the gas phase occurs in three regions of the spectrum. Rotational transitions are responsible for absorption in the microwave and far-infrared, vibrational transitions in the mid-infrared and near-infrared.

  4. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed. [1][2]: 3 [3][4][5][6] A more common definition in radio-frequency engineering ...

  5. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    Electromagnetic spectrum. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light ...

  6. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave transmission. The atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph corresponds to frequencies at which microwaves are absorbed more strongly, such as by oxygen molecules. Microwave transmission is the transmission of information by electromagnetic ...

  7. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Microwave chemistry is the science of applying microwave radiation to chemical reactions. [1][2][3][4][5] Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component ...

  9. Satellite temperature measurement - Wikipedia

    en.wikipedia.org/wiki/Satellite_temperature...

    Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites. These measurements can be used to locate weather fronts, monitor the El Niño-Southern Oscillation, determine the strength of tropical ...
