Polarisation
A light whose electric field vectors are completely removed by using a good polaroid, allowed to incident on the surface of the prism at Brewster's angle. Choose the most suitable option for the phenomenon related to the prism.
Show answer and solution
Answer: (d)
- The polaroid has removed the field component perpendicular to the plane of incidence, so the light vibrates only in the plane of incidence.
- At Brewster angle this component is not reflected at all.
- So there is no reflection and all light is transmitted: answer (d).
