The polarizing angle of glass is ( 57^ ). A ray of light which is incident at this angle will have an angle of refraction as

Options

  1. A25^
  2. B( 33^ )
  3. C( 43^ )
  4. D( 38^ )

Correct answer

B. ( 33^ )

Step-by-step solution

Given, polarising angle of glass, ( i_ p =57^ ) We know that, when the light is incident at polarising angle then reflected and refracted rays are at right angles to each other. Therefore, [ r=90^ -i_ p =90-57=33^ ] Therefore, angle of refraction is ( 33^ ).
