Spectral signature

Spectral signatures the difference in the reflectance/emittance characteristics with respect to wavelengths (i.e.,reflectance/emittance as a function of wavelength) is called as spectral signature. The spectral signature of stars indicates the composition of the stellar atmosphere. The spectral signature of an object is a function of the incidental EM wavelength and material interaction with that section of the electromagnetic spectrum.
