In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats. [1] [2] In other words, it is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings.
Learn what wavelength is, how to measure it, and how it relates to speed and frequency of waves. Find out how wavelength affects the Doppler effect and other phenomena in physics and astronomy.

11. Jan. 2020 · Learn what a wavelength is and how it relates to the speed and frequency of a wave. See examples of wavelengths of light and sound and how to calculate them.
Learn how to define and relate wave variables such as wavelength, frequency, period, and velocity. See examples of water waves, sound waves, and light waves, and how they are affected by energy and speed.
Learn how to measure the wavelength of a wave, a type of electromagnetic radiation, and how it relates to the frequency and energy of the wave. Find out how different types of waves, such as sound and light, have different wavelengths and how they vary with frequency.
5. März 2020 · A wave is a disturbance that moves energy from one place to another. 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. Frequency is how many waves pass one point during one second. Learn how scientists use these properties to describe different types of waves, such as light, sound and seismic.
