  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. 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).

  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 …

  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 - 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 …

  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 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.

  9. 1.2: Wavelengths and spectrum - Physics LibreTexts

    This page details the electromagnetic spectrum, focusing on visible light (400-700 nm) and its significance. It compares vision to other senses, explains color mixing (additive and …

  10. 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 …
