Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. Brewster’s law of polarization: As per the Brewster’s Law, the maximum polarization takes place when the angle between the reflected ray and refracted ray is 90⁰. It develops a relationship between the polarizing angle (ip) and the refractive index (μ) which states that the tangent of the polarizing angle is numerically equal to the refractive index of the medium. i.e., tan ip = μ Brewster’s angle (Polarizing angle): The angle of incidence at which an incident beam of unpolarized light gets completely polarized after reflection is known as Brewster’s angle or polarizing angle. Brewster’s law formula derivation: According to above Brewster’s law and above figure, ip + 90⁰ + r = 180⁰ ⇒ r = 90⁰ – ip From Snell’s law, μ = Sin ip/Sin r ⇒μ = Sin ip/Sin (90⁰ – ip) ⇒μ = Sin ⇒μ = /Cos ip ⇒μ = tan ip 1 Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp [Deleted User] 2020-11-13T13:04:02+00:00Added an answer on November 13, 2020 at 1:04 pm 1 Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp You must login to add an answer.
