emitting the same wavelength, as mentioned in this quote: «However, aerosols (which often contain water and if so can absorb red wavelengths) are usually larger than visible wavelengths and therefore absorb and reflect all wavelengths of
light equally (this is not technically scattering, although it is often called that; it technically involves absorption and re-radiation, or reflection).»
