By varying the size of the quantum dots, the cells can be tuned to absorb different wavelengths.

The ring structures absorb particular wavelengths of light, and thus appear colored.

Fish vision is mediated by four visual pigments that absorb various wavelengths of light.

Most objects appear to have color because their chemical structures absorb certain wavelengths of light and reflect others.

Each individual substance absorbs specific different wavelengths of visible light.

For example, a blue light filter appears blue because it absorbs red and green wavelengths.

The eye is acclimatized to seeing in poor light by having rods that absorb mostly low wavelengths.

All biological pigments selectively absorb certain wavelengths of light while reflecting others.

First, it must not absorb visible wavelengths of light.

Like a cloud of gas, or something, that blocks some of the light, absorbs specific wavelengths.
