Question

Quizplus · Accepted Answer

A spectral signature is a charted identifier for a feature based on its reflectance of different wavelengths of energy. Spectral reflectance refers to the amount of light reflected by a feature at different wavelengths. Spectral incidence refers to the angle at which energy (e.g. sunlight) strikes a feature, while spectral scattering refers to the way in which energy is dispersed or scattered by a feature. Therefore, the best choice is B - spectral signature.
