The Relative Reflectance of a Monolayer-Covered Water Surface

摘要

The analytical analysis of the reflectances of smooth film-covered water surfaces has shown that a film forming substance having the proper optical properties could significantly increase the reflectances of a water surface. The experimental studies showed that for certain wave lengths of energy of cetyl alcohol monolayer slightly increases the reflectance of the water surface, but that this is not a significant increase. The analytical study of the influence of water waves on the reflectance showed that the water waves do significantly influence the energy reflected from the surface and that, for cloudy conditions, the presence of large water waves can decrease the effective reflectance by approximately 50 per cent.
