  2. Wave action (continuum mechanics) - Wikipedia

    en.wikipedia.org/wiki/Wave_action_(continuum...

    This wind wave model generates forecasts of wave conditions through the use of wave-action conservation and the wind-field forecasts (from weather forecasting models). [1] In continuum mechanics, wave action refers to a conservable measure of the wave part of a motion. [2] For small-amplitude and slowly varying waves, the wave action density is ...

    ROYGBIV (in reverse VIBGYOR) is commonly used to remember the order of colors in the visible light spectrum, as seen in a rainbow. Richard of York gave battle in vain" (red, orange, yellow, green, blue, indigo, violet). Additionally, the fictitious name Roy G. Biv can be used as well. (red, orange, yellow, green, blue, indigo, violet).

  4. Classical electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Classical_electromagnetism

    A changing electromagnetic field propagates away from its origin in the form of a wave. These waves travel in vacuum at the speed of light and exist in a wide spectrum of wavelengths . Examples of the dynamic fields of electromagnetic radiation (in order of increasing frequency): radio waves , microwaves , light ( infrared , visible light and ...

    en.wikipedia.org/wiki/Wave_setup

    Incidentally, due to this phenomenon, a small reduction in water level occurs just seaward of the breaker line, in the order of 20% of the wave set-up. The wave setup at ocean beaches can be significant. For example, a wave with a height of 5 m (on deep water) and a period of 12 s, at perpendicular incidence and γ = 0.7, gives a wave setup of ...

  6. 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 ...

  7. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    Each has an energy related to the frequency of the wave given by Planck's relation E = hf, where E is the energy of the photon, h is the Planck constant, 6.626 × 10 −34 J·s, and f is the frequency of the wave. [40] In a medium (other than vacuum), velocity factor or refractive index are considered, depending on frequency and application ...

  9. Wave turbulence - Wikipedia

    en.wikipedia.org/wiki/Wave_turbulence

    Two generic types of wave turbulence should be distinguished: statistical wave turbulence (SWT) and discrete wave turbulence (DWT). In SWT theory exact and quasi-resonances are omitted, which allows using some statistical assumptions and describing the wave system by kinetic equations and their stationary solutions – the approach developed by Vladimir E. Zakharov.
