Question

The Brewsters angle $i_b$ for an interface should be:

• A. $0°< i b < 30°$
• B. $30°< i_b < 45°$
• C. $45°< i_b < 90°$
• D. $i_b = 90°$

Answer 1

The Correct Option is C

$\mu=tan\,i_{b}$ $1<\,\mu<\,\infty$ $1<\,tan\,i_{b}<\,\infty$ $tan^{-1}\left(1\right)<\,i_{b}<\,tan^{-1}\left(\infty\right)$ $45^{\circ}<\,i_{b}<\,90^{\circ}$
