wavelength
spatial period of the wave; the distance over which the wave's shape repeats; the inverse of the spatial frequency
dominant wavelength
any monochromatic spectral light that evokes the corresponding opposite perception of hue
photosynthetically active radiation
range of light usable for photosynthesis
de Broglie wavelength
wavelength of a massive particle according to de Broglie hypothesis
passband
frequencies or wavelengths that can pass through a filter
Compton wavelength
in quantum mechanics, the wavelength of a photon whose energy is the same as the rest energy of a particle
