  1. Wavelength - Wikipedia

    Wavelength is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. [3][4] The inverse of the wavelength is called the spatial frequency.

  2. Wavelength - Center for Science Education

    The wavelength of a wave describes how long the wave is. The distance from the "crest" (top) of one wave to the crest of the next wave is the wavelength. Alternately, we can measure from …

  3. Wavelength | Definition, Formula, & Symbol | Britannica

    Nov 21, 2025 · Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v / f.

  4. Wavelength - Physics Book

    Dec 3, 2023 · Wavelength is usually determined by measuring the distance between repeating patterns. Wavelength is commonly designated by the Greek letter, lambda (λ), and the SI unit …

  5. What is a wavelength? - HowStuffWorks

    The wavelength is calculated by determining the distance between corresponding points on consecutive waves. Normally this is done by measuring from peak to peak or from trough to …

  6. Wavelength – light, wavenumber, plane waves, optical …

    A wavelength is the spatial period of a plane wave, e.g. of light. Wavelengths are related to frequencies. Optical wavelengths can apply to vacuum, air or some other medium.

  7. The Electromagnetic Spectrum - NASA Earthdata

    Dec 19, 2025 · Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of space. These waves have …

  8. Wavelength - Laboratory Notes

    Aug 5, 2025 · Wavelength is a fundamental concept in wave physics, describing the spatial distance between two successive points in phase on a wave—typically measured from crest to …

  9. Wavelength -- from Eric Weisstein's World of Physics - Wolfram

    The wavelength of a wave is the distance between corresponding points separated by one period. It is commonly denoted \lambda, and given by \lambda = {v\over\nu}, where v is the wave …

  10. Wavelength (λ) – Definition, Formula, and Scientific Use

    Apr 29, 2025 · Learn what wavelength means in physics and engineering. Includes formulas for electromagnetic and mechanical waves, plus real-world applications across disciplines.
