We do an experiment with various transparent cylindrical rods made of different refractive indices and place it on ruled white paper of a usual exercise book. If the rod is placed with its axis at some angle \(\theta=\frac{\pi}{4}
\) the lines appear broken and tilted at some angle
\(\alpha
\)
The minimum refractive index of the glass that shows this phenomenon at this angle \(\theta=\frac{\pi}{4}
\) is \(\mu_{o}
\) and gives an deviation \(\alpha=\alpha_{1}
\) find \(\mu_{o}\alpha_{1}
\) where \(\alpha_{1}
\)is in radian
