Figure 2. Reflectance spectra measured by laboratory spectrometers for three materials: a green bay laurel leaf, the mineral talc, and a silty loam soil. Field and laboratory spectrometers usually measure reflectance at many narrow, closely spaced wavelength bands, so that the resulting spectra appear to be continuous curves (Fig. 2).
