Question: ${V_o}$and ${V_E}$represent the velocities,${\mu _o}$and${\mu _E}$the refractive indices of ordinary and extraordinary rays for a doubly refracting crystal. Then



1) ${V_o} \ge {V_E},\;\;{\mu _o} \le {\mu _E}$if the crystal is calcite
2) ${V_o} \le {V_E},\;\;{\mu _o} \le {\mu _E}$if the crystal is quartz
3) ${V_o} \le {V_E},\;\;{\mu _o} \ge {\mu _E}$if the crystal is calcite
4) ${V_o} \ge {V_E},\;\;{\mu _o} \ge {\mu _E}$if the crystal is quartz
