STANDARD Physics Polarization MCQ Question
Type: MCQ-conceptual-Medium-Class 12
When unpolarised light is incident on a surface at a particular angle of incidence 'i', it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation?
A
Reflected light is polarised with its electric vector parallel to the plane of incidence
B
Reflected light is polarised with its electric vector perpendicular to the plane of incidence
C
i = tan⁻¹(1/μ)
D
i = sin⁻¹(1/μ)
Correct Answer
Option B
Detailed Explanation
The Reflected ray of light, when the angle of incidence is Brewster angle, would comprise of only the other component of light wave which is oscillating in a direction perpendicular to vibration of electric field vectors.
