Best answer


Brewster鈥檚 law is arelationship of light waves at the maximum polarization angle of light. This law is named after Sir David Brewster, a Scottish physicist, who proposed the law in the year 1811. The law states that the p-polarized rays vanish completely on different glasses at a particular angle.

  • What is Brewster鈥檚 law?

  • Brewster鈥檚 law is a relationship of light waves at the maximum polarization angle of light. This law is named after Sir David Brewster, a Scottish physicist, who proposed the law in the year 1811. The law states that the p-polarized rays vanish completely on different glasses at a particular angle.

  • What is Brewster’s law of refraction?

  • Brewster鈥檚 law, relationship for light waves stating that the maximum polarization (vibration in one plane only) of a ray of light may be achieved by letting the ray fall on a surface of a transparent medium in such a way that the refracted ray makes an angle of 90 with the reflected ray.

  • What is Brewster鈥檚 angle of incidence?

  • The angle of incidence obtained by Brewster鈥檚 Law is called Brewster鈥檚 angle or polarization angle. When the reflected and refracted rays are perpendicular to each other the light ray reflected off the refracting surface is completely polarized perpendicular to the refracting plane.

  • What will be Brewster鈥檚 angle of light?

  • What will be Brewster鈥檚 angle of light, if the light travels from water into the air. Assume that n = 1.33. Therefore, Brewster鈥檚 angle is 48.4o. Determine the angle of refraction and polarization angle of the polarizer if the refractive index of the polarizer is 1.33.
