SUMMARY
The angle of strongest polarization of light reflecting off a smooth lake occurs at Brewster's angle, which is approximately 56.31 degrees above the horizon for sunlight. This angle is derived from Brewster's law, which states that the angle of incidence at which light is perfectly polarized upon reflection is given by the formula tan(θ_B) = n, where n is the refractive index of the water. At this angle, the reflected light is maximally polarized, making it essential for understanding optical phenomena in water bodies.
