WebMESSENGER scientists refer to this as the "Low Reflectance Material (LRM)." Besides being dark across all wavelengths, the LRM reflects less light at longer wavelengths than does average Mercury material. Our eyes perceive light at the long wavelength end of the visible spectrum as red, and the short end as blue. WebThere are no solid materials with such a low refractive index.
