    Water absorbs the infrared waves and hence doesn't reflect anything in infrared region.(so seen as black false color composite) Soil absorbs lower wavelength radiations and reflectance amount increases with wavelength of radiation as shown in the attached figure. Vegetation gives maximum reflectance in near infrared region and absorbs the other wavelength as shown in the spectral curve diagram.(green color composite)
