Consider the following statements regarding unpolarized light incident on a transparent medium at Brewster's angle: (A) The reflected and refracted rays are mutually perpendicular. (B) The reflected wave is completely polarized with its electric field vector parallel to the plane of incidence. (C) The transmitted wave is partially polarized. (D) Brewster's angle is strictly independent of the color (wavelength) of th

Step-by-step solution

At Brewster's angle, the reflected and refracted rays are perpendicular to each other, making statement (A) correct. The reflected light is completely plane-polarized with its electric field vector perpendicular to the plane of incidence, so statement (B) is incorrect. The transmitted (refracted) light is partially polarized, making statement (C) correct. According to Brewster's law, (i_p) = . Since the refractive index depends on the wavelength of light (due to dispersion), Brewster's angle also depends on the col
