*the wavelength of a sine wave, λ, can be measured between any 2 points with the same phase, such as between crests (on top), or troughs (on bottom), or corresponding zero crossings as shown*
.
-as of [21 SEPTEMBER 2024]-
.
*in ‘physics’, the wavelength of a ‘sinu-soidal wave’ is the spatial period of the wave…*
*the distance over which the wave’s shape repeats*
*the inverse of the ‘spatial frequency’*
.
(it is usually determined by considering the distance between ‘consecutive corresponding points’ of the same ‘phase’ (such as ‘crests’ / ‘troughs’ / ‘zero crossings’ and is a characteristic of both ‘traveling waves’ + ‘standing waves’, as well as other ‘spatial wave patterns’)
(‘wavelength’ is commonly designated by the greek letter lambda (λ))
(the concept can also be applied to ‘periodic’ waves of ‘non-sinusoidal’ shape)
(the term wavelength is also sometimes applied to ‘modulated waves’, and to the ‘sinusoidal envelopes’ of ‘modulated waves’ or waves formed by interference of several ‘sinusoids’)
(assuming a ‘sinusoidal wave’ moving at a ‘fixed wave speed’, ‘wavelength’ is ‘inversely proportional’ to ‘frequency’ of the wave…)
(waves with ‘higher frequencies” have ‘shorter wavelengths’)
(and ‘lower frequencies’ have ‘longer wavelengths’)
(‘wavelength’ depends on the ‘medium’ (for example, (‘vacuum’ / ‘air’ / ‘water’) that a wave travels through)
(examples of ‘wave-like phenomena’ are (‘sound’ / ‘light’ / ‘water’) waves)
(a ‘sound wave’ is a variation in ‘air pressure’, while in ‘light’ and other ‘electromagnetic radiation’ the strength of the ‘electric field’ and the ‘magnetic field’ vary)
(‘water waves’ are variations in the height of a ‘body of water’)
(in a ‘crystal lattice vibration’, ‘atomic positions’ vary)
(‘wavelength’ is a measure of the distance between repetitions of a shape feature such as (‘peaks’ / ‘valleys’ / ‘zero-crossings’), not a measure of how far any given particle moves)
(for example, in ‘sinusoidal waves’ over ‘deep water’ a particle near the water’s surface moves in a ‘circle’ of the same ‘diameter’ as the ‘wave height’, unrelated to ‘wavelength’)
(the range of ‘wavelengths’ or ‘frequencies’ for ‘wave phenomena’ is called a ‘spectrum’)
.
(the name originated with the ‘visible light spectrum’ but now can be applied to the entire ‘electro-magnetic spectrum’ as well as to a ‘sound spectrum’ / ‘vibration spectrum’)
