When the un-polarised light beam is incident from air to glass at the Brewster's angle,
Options
- Areflected beam is polarized .
- Breflected and refracted beams are partially polarized.
- Creflected beam is polarized .
- Drefracted beam is polarized
Correct answer
C. reflected beam is polarized .
Step-by-step solution
According to Brewster's law, when an unpolarized light beam is incident on a transparent medium at the Brewster's angle, the reflected light is completely plane-polarized with its electric field vector perpendicular to the plane of incidence.
The refracted light remains partially polarized.
Therefore, the reflected beam is polarized.
Answer: reflected beam is polarized .
The refracted light remains partially polarized.
Therefore, the reflected beam is polarized.
Answer: reflected beam is polarized .
