A ray of light is incident on a surface of glass slab at an angle 45^{\circ}. If the lateral shift produced per unit thickness is {1}/{\sqrt{3}} {\m}, the angle of refraction produced is

Correct Answer is : tan−1(1−√23)

\tan ^{-1} (1-\sqrt{\frac{2}{3}})

\sin ^{-1} (1-\sqrt{\frac{2}{3}})

\tan ^{-1} (\sqrt{ {2}/{\sqrt{3}-1}})
