THE BREWSTER’S ANGLE IB FOR AN INTERFACE SHOULD BE

(a) 0° < i_b<30°

(b) 30° < i_b<45°

(d) i_b= 90°

Brewster’s law:

when unpolarized light falls on an interface, the reflected light is completely polarized if the angle of incidence is a specific angle called the Brewster's angle.

Brewster's law is a statement that says that, the refractive index of the material is equal to the tangent of Brewster’s angle (polarizing angle)

According to the Brewster’s law

\[\mu =\tan i_{b}\]

\[1<\mu <\infty\]

\[1<\tan i_{b} <\infty\]

\[\tan^{-1}1<i_{b}<\tan^{-1}\infty\]

\[45^{o}<i_{b}<90^{o}\]

Answer: Option ‘C’
