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}, then 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{\frac{2}{3-1}})
