  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 - 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. 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 …

  6. What Is Wavelength? - BYJU'S

    The wavelength of light is defined as “The distance between the two successive crests or troughs of the light wave”. It is denoted by the Greek letter lambda (λ).

  7. Wavelength Calculator λ = v/f

    Aug 1, 2025 · Wavelength is the distance between 2 identical points on a sinusoidal wave. If you know the frequency of a wave traveling through a medium you can calculate how far it is …

  8. Frequency and Wavelength: Formula, Relation & Examples for …

    Wavelength is the spatial distance over which the wave's shape repeats, measured in meters or its derivatives. As frequency increases, wavelength decreases, and vice versa, as long as the …

  9. Visible Light Spectrum Wavelengths and Colors

    Jan 16, 2021 · It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum. Ultraviolet light and x-rays are the …

  10. 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 …
