  2. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    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, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each of these bands have different characteristics, such as how they are ...

  3. Infrared - Wikipedia

    en.wikipedia.org/wiki/Infrared

    The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally understood to include wavelengths from around 667 nm (449 THz ) to 1 mm (300 GHz ).

  4. Remote sensing (oceanography) - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_(oceanography)

    Ocean waves crash or disappear before a new observation is made, features with this time scale are rarer on land. Unlike vegetation, snow and other land covers the ocean is opaque to most electromagnetic radiation [ 9 ] (except for visible light) therefore the ocean surface is easy to monitor but it is a challenge to retrieve information of ...

  5. Oceanography - Wikipedia

    en.wikipedia.org/wiki/Oceanography

    Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.

  6. Infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Infrared_spectroscopy

    The infrared portion of the electromagnetic spectrum is usually divided into three regions; the near-, mid- and far-infrared, named for their relation to the visible spectrum. The higher-energy near-IR, approximately 14,000–4,000 cm −1 (0.7–2.5 μm wavelength) can excite overtone or combination modes of molecular vibrations .

  7. Outline of oceanography - Wikipedia

    en.wikipedia.org/wiki/Outline_of_oceanography

    The following outline is provided as an overview of and introduction to Oceanography.. Thermohaline circulation. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.

  8. Ocean optics - Wikipedia

    en.wikipedia.org/wiki/Ocean_optics

    Ocean optics is the study of how light interacts with water and the materials in water. Although research often focuses on the sea, the field broadly includes rivers ...

  9. Electromagnetic absorption by water - Wikipedia

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

    The gaps between the bands define the infrared window in the Earth's atmosphere. [17] The infrared spectrum of liquid water is dominated by the intense absorption due to the fundamental O-H stretching vibrations. Because of the high intensity, very short path lengths, usually less than 50 μm, are needed to record the spectra of aqueous solutions.
