Polarisation
An unpolarised light beam strikes a glass surface at Brewster's angle. Then
Show answer and solution
Answer: (d)
- At Brewster's angle the reflected light has only the component perpendicular to the plane of incidence, so it is completely polarised.
- The refracted light contains both components (only part of one is removed), so it is partially polarised.
- So the answer is (d) the reflected light will be completely polarised but the refracted light will be partially polarised.
