At what angle in degrees should a ray of light be incident on the face of a prism of refracting angle $60^{o}$ so that it just suffers total internal reflection at the other face? The refractive index of the material of the prism is $1.524$ . Given $s i n^{- 1} (0.66) = 41^{o}$ , $sin 19^{o} = 0.3256$ , ${sin}^{- 1} (0.4962) = 30^{o}$ , $\frac{1}{1.5424} = 0.66$
