हिन्दीThe Brewster’s angle \( i_b \) for an interface should be:
Correct answer · Option 2
\( 45^\circ < i_b < 90^\circ \)
Explanation
Since \( \mu = \tan i_b \), as refractive index \( \mu > 1 \) for all practical transparent media, \( i_b > 45^\circ \). Also, angle of polarization must be less than \( 90^\circ \), hence \( 45^\circ < i_b < 90^\circ \).
