In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling … See more In linear media, any wave pattern can be described in terms of the independent propagation of sinusoidal components. The wavelength λ of a sinusoidal waveform traveling at constant speed $${\displaystyle v}$$ is … See more The term subwavelength is used to describe an object having one or more dimensions smaller than the length of the wave with which the object interacts. For example, the term subwavelength-diameter optical fibre means an optical fibre whose diameter is less … See more • Emission spectrum • Envelope (waves) • Fraunhofer lines – dark lines in the solar spectrum, traditionally used as standard optical wavelength references See more The concept of wavelength is most often applied to sinusoidal, or nearly sinusoidal, waves, because in a linear system the sinusoid is the … See more Double-slit interference When sinusoidal waveforms add, they may reinforce each other (constructive interference) or … See more A quantity related to the wavelength is the angular wavelength (also known as reduced wavelength), usually symbolized by ƛ (lambda-bar). It is equal to the "regular" wavelength "reduced" by a factor of 2π (ƛ = λ/2π). It is usually encountered in quantum … See more • Conversion: Wavelength to Frequency and vice versa – Sound waves and radio waves • Teaching resource for 14–16 years on sound including wavelength See more WebChromatic dispersion is a measure of the degree to which the effective propagation velocity changes as a function of wavelength.
