When a light ray incidents on the surface of a medium, the reflected ray is completely polarized. Then the angle between reflected and refracted rays is

Options

  1. A45^
  2. B90^
  3. C120^
  4. D180^

Correct answer

B. 90^

Step-by-step solution

According to Brewester's law if the reflected ray is completely polarized, then the reflected and refracted ray is perpendicular to each other. Thus, =90^
