Question

The Brewsters angle \(i_{b}\) for an interface should be:
A \(0^{\circ}<i b<30^{\circ}\)
В \(30^{\circ}<i_{b}<45^{\circ}\)
c) \(45^{\circ}<i_{b}<90^{\circ}\)
D \(i_{b}=90^{\circ}\)

Answer 1

Solution:
$$
\begin{aligned}
&\mu=\tan i_{b} \\
&1<\mu<\infty \\
&1<\tan i_{b}<\infty \\
&\tan ^{-1}(1)<i_{b}<\tan ^{-1}(\infty) \\
&45^{\circ}<i_{b}<90^{\circ}
\end{aligned}
$$
