{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

View answer and explanation

Correct option: C

{V_o} \le {V_E},{\mu _o} \ge {\mu _E}

if the crystal is calcite

Option C (

{V_o} \le {V_E},{\mu _o} \ge {\mu _E}

if the crystal is calcite) is correct because for calcite, the refractive index of the ordinary ray is greater than or equal to that of the extraordinary ray, and the velocity is inversely related.
