| White reflects all wavelengths evenly, but a blue surface reflects only blue and absorbs red and green. |
| This red shift should result in different relative emissions at different wavelengths. |
| Like its brighter and fast-moving relative the aurora, night airglow has strong emissions at specific wavelengths. |
| More important than their reflection of light is the ability of pigments to absorb certain wavelengths. |
| Unfortunately, Earth's atmosphere blocks almost all wavelengths in the electromagnetic spectrum. |
| At these wavelengths, Rayleigh scattering is also reduced, increasing visual clarity. |
