Abstract

To determine one effect that an absorption coefficient, represented by the imaginary portion of the index of refraction, has on reflectance, the computed reflectance for the real values of the index of refraction was compared with the value of index of fraction equal to zero. the values of the imaginary portion of the index of refraction less than 0.02 have no effect on the reflectance from a water surface. It therefore can be assumed in computing reflectance that, except for the X absorption bands in the near infrared and all of the far infrared, water is a perfect nonconductor. to determine effect that an absorption coefficient, represented by the imaginary portion of the index of refraction, has on reflectance, the computed reflectance for the real values of the index of refraction was compared with the value of index of fraction equal to zero.
