Question

$V_o \hspace{3} and \hspace{3} V_E$ represent the velocities, $V_o \hspace and \hspace{3} V_E$ the refractive indices of ordinary and extraordinary rays for a doubly refracting crystal. Then
(a) $V_o \geq V_E , \mu_o \leq \mu_E$ if the crystal is calcite
(b) $V_o \leq V_E , \mu_o \leq \mu_E$ if the crystal is quartz
(c) $V_o \leq V_E , \mu_o \geq \mu_E$ if the crystal is calcite
(d) $V_o \geq V_E , \mu_o \geq \mu_E$ if the crystal is quartz
