A) \[{{V}_{o}}\ge {{V}_{E}},\ \ {{\mu }_{o}}\le {{\mu }_{E}}\]if the crystal is calcite
B) \[{{V}_{o}}\le {{V}_{E}},\ \ {{\mu }_{o}}\le {{\mu }_{E}}\]if the crystal is quartz
C) \[{{V}_{o}}\le {{V}_{E}},\ \ {{\mu }_{o}}\ge {{\mu }_{E}}\]if the crystal is calcite
D) \[{{V}_{o}}\ge {{V}_{E}},\ \ {{\mu }_{o}}\ge {{\mu }_{E}}\]if the crystal is quartz
Correct Answer: C
Solution :
In double refraction light rays always splits into two rays (O-ray & E-ray). O-ray has same velocity in all direction but E-ray has different velocity in different direction. For calcite me < m0 Þ ve > v0 For quartz me > m0 Þ v0 > veYou need to login to perform this action.
