Light in air strikes a glass plate with refractive index at Brewster's angle . What is the angle of refraction inside the glass?
Answer and explanation
Correct answer: A. 33,7°
- Step 1: Brewster's law: . Step 2. At Brewster's angle, reflected and refracted rays are perpendicular: . Step 3. . Answer: Angle of refraction is 33,7°. Why not the others: Reflected and refracted rays form a 90° angle at Brewster's polarization.
