QNEET-2020-Ph-719: NEET 2020 Physics - Class 12 NEET-2020-Ph-719 Solution: The Brewster's angle \(i_b\) for an interface should be: \(30^…

The Brewster's angle ibi_b for an interface should be: 30∘<ib<45∘30^\circ < i_b < 45^\circ 45∘<ib<90∘45^\circ < i_b < 90^\circ ib=90∘i_b = 90^\circ 0∘<ib<30∘0^\circ < i_b < 30^\circ

Multiple Choice Options

  • A 30 ∘^\circ _ < i b < 45 ∘^\circ _
  • B 45 ∘^\circ _ < i b < 90 ∘^\circ _
  • C i b = 90 ∘^\circ _
  • D 0 ∘^\circ _ < i b < 30 ∘^\circ _

Step-by-Step Verified Solution

Refractive index _ is equal to tangent of Brewster's angle i b _ = tan i b 1 < _ < � 1 < tan i b < � tan -1 (1) < i b < tan -1 ( � ) 45 _ < i b < 90 _
