367906 The Brewster’s angle for the glass - air interface is \(\left( {54.74} \right)^\circ \). If a ray of light passing from air to glass strickers at an angle of incidence \(45^\circ \), then the angle of refraction is
\(\left[ {\tan \left( {54.74} \right)^\circ = \sqrt 2 ,\sin 45 = \frac{1}{{\sqrt 2 }}} \right]\)
