  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 | 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.

  3. 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 of wavelength is …

  4. 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 the "trough" …

  5. Wavelength Definition - Principles of Physics II Key Term | Fiveable

    Wavelength affects how light interacts with materials; for instance, different wavelengths can be absorbed, reflected, or transmitted differently by substances.

  6. WAVELENGTH Definition & Meaning - Merriam-Webster

    The meaning of WAVELENGTH is the distance in the line of advance of a wave from any one point to the next point of corresponding phase. How to use wavelength in a sentence.

  7. 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.

  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 crest or trough …

  9. Explainer: Understanding waves and wavelengths - Science News …

    Mar 5, 2020 · Wavelength is the distance from one point on a wave to an identical point on the next, such as from crest to crest or from trough to trough. Waves can come in a wide range of lengths.

  10. What Is a Wavelength? Definition and Examples - ThoughtCo

    Jan 11, 2020 · The distance between one crest (or trough) of one wave and the next is the wavelength of the wave. In equations, wavelength is indicated using the Greek letter lambda (λ).
