The 15 pages that link to Wavenumber, each with the reason it gives.

• WavelengthRelated: It expresses the same spatial scale as wavelength in reciprocal form.

• Infrared spectroscopyRelated: Infrared spectra conventionally place wavenumber on the horizontal axis.

• Phase velocityRelated: It supplies the spatial rate in the defining frequency-to-wavenumber ratio.

• Group velocityRelated: It is the variable with respect to which angular frequency is differentiated.

• Rydberg formulaRelated: The Rydberg equation is often written most simply as a difference in wavenumber.

• Periodic boundary conditionRelated: On a periodic interval, allowed wave numbers are often quantized by endpoint matching.

• Fourier-transform infrared spectroscopyRelated: FTIR spectra conventionally assign band positions using wavenumbers, usually in inverse centimeters.

• Hydrogen spectral seriesRelated: The Rydberg formula expresses hydrogen transition energies directly in terms of wavenumber.

• DispersionRelated: Its dependence on angular frequency encodes a wave’s dispersion relation.

• Paraxial approximationRelated: It sets the longitudinal carrier scale against which envelope variation is judged.

• Helmholtz equationRelated: Its square is the constant that sets the equation’s oscillation scale.

• Rydberg constantNarrower topic: The Rydberg constant is expressed as a wavenumber.

• Johannes RydbergRelated: Rydberg expressed spectral regularities using wavenumbers, where the series become simple.

• Wave vectorRelated: It is the wave vector’s magnitude and sets the rate of phase change along propagation.

• Rotational–vibrational spectroscopyRelated: Rovibrational line positions are conventionally reported in wavenumbers.
