When unpolarised light is incident on a plane glass plate at Brewster’s (polarising) angle, then which of the following statements is correct?
- reflected and refracted rays are completely polarised with their planes of polarisation parallel to each other.
- reflected and refracted rays are completely polarised with their planes of polarisation perpendicular to each other
- the reflected light is plane polarised but transmitted light is partially polarised
- the reflected light is partially polarised but refracted light is plane polarised.
Answer
(C) the reflected light is plane polarised but transmitted light is partially polarised
