wavelength the distance, measured in the direction of propagation, between two points of the same phase in consecutive cycles of a wave. Wavelength The distance between two points on a wave which have the same value and the same rate of change of the value of a parameter, for example, electric intensity, characterizing the wave. The wavelength, usually designated by the Greek letter λ, is equal to the speed of propagation c of the wave divided by the frequency of vibration f; that is, λ = c/f (see illustration). See Wave (physics), Wave motion  Wavelength λ and related quantitieswavelength (wayv -length) Symbol: λ. The distance over which a periodic wave motion goes through one complete cycle of oscillation, i.e. the distance traveled during one period. Thus for a sinusoidal wave motion, such as electromagnetic radiation, it is the distance between two successive peaks or troughs. For electromagnetic radiation, wavelength is related to frequency, ν, by νλ = c , where c is the speed of light. Wavelength is measured in meters or in multiples or submultiples of meters; for example, the wavelength of light is usually given in nanometers while that of infrared radiation is usually quoted in micrometers.wavelength[′wāv‚leŋkth] (physics) The distance between two points having the same phase in two consecutive cycles of a periodic wave, along a line in the direction of propagation. wavelengthFor light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. For light waves three common units of wavelength are: micrometer, nanometer, and angstrom.wavelengthThe distance between crests of a wave. The wavelength determines the nature of the various forms of radiant energy that comprise the electromagnetic spectrum. For electromagnetic waves, the wavelength in meters is computed by the speed of light divided by frequency (300,000,000/Hz). For sound waves, the wavelength is determined by 335/Hz. See optical bands.

wavelength
wavelength [wāv´length] the distance between the top of one wave and the identical phase of the succeeding one in the advance of waves of radiant energy.wave·length (Λ), (wāv'length), The distance from one point on a wave (frequently shaped like a sine curve) to the next point in the same phase; that is, from peak to peak or from trough to trough.wave·length (λ) (wāv'length) The distance from one point on a wave (frequently shaped like a sine curve) to the next point in the same phase; i.e., from peak to peak or from trough to trough. wavelength the distance between two successive points at which the wave has the same phase. For example, visible light has a wavelength of between 400 nm (violet) to 750 nm (red).wavelength Distance in the direction of propagation of a periodic wave between two successive points at the same position in the wave (e.g. the distance between two crests). Symbol: λ. Note 1: The wavelength in a medium is equal to the wavelength in vacuum divided by the refractive index of the medium. Unless otherwise stated, values of wavelength are generally those in air. The refractive index of standard air (15ºC, 101 325 N/m2) lies between 1.00027 and 1.00029 for visible radiations. Note 2: The reciprocal of the wavelength is called the wave number. Note 3: The wavelength is longer for red light than for blue light. Wavelength λ is equal toλ = c/vwhere c is the velocity of light and v is the frequency of light.

" > Fig. W1 Wavelength of light in air and in a medium of refractive index n1 and n2, respectively (λ2 = λ1/n2)wave·length (wāv'length) The distance from one point on a wave (frequently shaped like a sine curve) to the next point in the same phase; i.e., from peak to peak or from trough to trough.
