We observe that even though the KdV equation and the BBM equation are valid at the same level of approximation, the group velocity of linear waves for the BBM equation is bounded for all wavenumbers while the group velocity of linear waves for the KdV equation has no lower bound.

Since the absorption is based on the vibration mode of atoms and very specific, therefore each peak at different wavenumber represents only to specific functional group (Alexander and Bell, 1972).
To make a spectrum easier to read, the usual practice is to show the wavelength as a wavenumber, the reciprocal of the wavelength.
