Question:
A ray of unpolarised light is incident on a glass plate at the polarising angle of $57^\circ$.
A ray of unpolarised light is incident on a glass plate at the polarising angle of $57^\circ$.
Show Hint
The polarising angle ensures complete polarisation of the reflected ray.

- both the reflected and transmitted rays will be completely polarised
- the reflected ray will be completely polarised and transmitted ray will be partially polarised
- the reflected ray will be partially polarised and transmitted ray will be completely polarised
- both the reflected and transmitted rays will be partially polarised
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
At the polarising angle, the reflected ray will be completely polarised and the transmitted ray will only be partially polarised. This occurs because the angle of incidence at the polarising angle produces a reflected ray that is fully polarised.
