When a ray is incident on a medium of refractive index $n$ at Brewster's angle, it gets
Show Hint
At Brewster's angle, the reflected light is completely polarized perpendicular to the plane of incidence.
Updated On: Apr 8, 2026
- totally reflected
- totally absorbed
- circularly polarised
- plane polarised
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Brewster's law relates the angle of incidence for which reflected light is completely polarized.
Step 2: Detailed Explanation:
According to Brewster's law, when unpolarised light is incident at the polarizing angle ($i_p = \tan^{-1}n$), the reflected light is completely plane-polarized.
Step 3: Final Answer:
The ray gets plane polarised.
