When unpolarised light beam is incident from air onto glass \((n=1.5)\) at the polarising angle
- A reflected beam is polarised 100 percent
- B reflected and refracted beams are partially polarised
- C the reason for (a) is that almost all the light is reflected
- D All of the above
Answer & Solution
Correct Answer
(A) reflected beam is polarised 100 percent
Step-by-step Solution
Detailed explanation
According to phenomena of polarisation by reflection, when unpolarised light beam is incident from air onto glass \((n=1.5)\) at the polarising angle (Brewster's angle), then reflected beam is polarised completely i.e. \(100 \%\).
