A transparent solid cylindrical rod has a refractive index of 2/√3. It is surrounded by air. A light ray is incident at the mid-point of one end of the rod as shown in the figure. Image related to The incident angle θ for which the light ray grazes along the wall of the rod is
\[sin^{-1}(1/2)\]
\[sin^{-1}(\sqrt{3}/2)\]
\[sin^{-1}({2}/\sqrt{3})\]
\[sin^{-1}({1}/\sqrt{3})\]
