Polarization of Light

Problem 5.168

A plane beam of natural light with intensity \(I_{0}\) falls on the surface of water at the Brewster angle. A fraction \(\rho=0.039\) of luminous flux is reflected. Find the intensity of the refracted beam.

Reveal Answer
I=I0(1−ρ)/n=0.721I0, where n is the refractive index of waterI=I_{0}(1-\rho) / n=0.721 I_{0}, \text { where } n \text { is the refractive index of water}
