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.
(A)Reflected and refracted rays will be perpendicular to each other
(B)Wave will propagate along the surface of prism
(C)No refraction, and there will be total reflection of light.
(D)No reflection and there will be total transmission of light.✓ Correct
Answer: (D)
Solution
At Brewster's angle, the reflected ray is completely polarized perpendicular to the plane of incidence. If the incident light has its electric field vectors completely removed (i.e., no component perpendicular to the plane of incidence), then there is no reflected light — only total transmission occurs. This is a special case discussed in NCERT where the incident polarization is parallel to the plane of incidence, resulting in complete transmission with no reflection.
