"by what factor may the glare off water be reduced when the sun is at(adsbygoogle = window.adsbygoogle || []).push({});

a) 45 degrees above the horizon

b)60 degrees above the horizon

n.b refractive index of water is 1.33"

I have derived the fresnel reflection coefficients for the cases when E is perpendicular to the plane of incidence, and when E is parallel to the plane of incidence. I am also assuming that "glare" is caused by the E-field. But I'm not sure which reflection coeffient to use i.e do we assume that E is parallel to plane of incidence of perp.?

thanks
