Question

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.

Answer 1

Answer: (D)

But as the incident light electric field vectors are completely removed so there will be no reflection and there will be total transmission of light, explained by an experiment in NCERT.
[Reference NCERT Part-2 Pg-380, (A special case of total transmission)]
Note : Since direction of polarization is not mentioned hence most suitable option (D) corresponding to case in which electric field is absent perpendicular to plane consisting incident and normal.
