PhysicsNEET 2020Diffraction and polarisation

Wave Optics

Brewster's angle $i_{b}$ for an interface should be:

A. $0^{\circ} < i_{b} < 3 0^{\circ}$
B. $3 0^{\circ} < i_{b} < 4 5^{\circ}$
C. $4 5^{\circ} < i_{b} < 9 0^{\circ}$ ✓
D. $i_{b} = 9 0^{\circ}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
