When I view the sea surface for a few seconds (using a camera), some wave facets have very high radiance values. I understand that there is a distribution of slopes and that one can determine a statistical radiance distribution, but how do I calculated the reflected radiance from a single wave facet with a certain orientation?

Google for "Fresnel's equations" which give the reflected and transmitted intensities of electromagnetic waves at a boundary, as a function of angle.
