Abstract
It is important to know the light reflected from the sea surface for the knowledge of the albedo of radiation of the sea surface. The measurements of the light reflected from the roughened surface of the wind disturbed ocean are too difficult to be carried out, and the problem may be made accessible to the experimental treatment by using a small wind tunnel containing a water boundary. The results show that Fresnel's law may be applicable not only for the smooth surface, but also for the roughened wavy surface by considering the individual wave slopes as the reflected plane of the incident light. Referentially, the changes in the mean values of the albedo with the latitude of the earth are represented for the smooth surface and for three wavy surfaces by application of the above results.
