represent the velocities, the refractive indices of ordinary and extraordinary rays for a doubly refracting crystal. Then
View answer and explanation
Correct option: C
if the crystal is calcite
For a calcite crystal, the refractive index for the ordinary ray is greater than that for the extraordinary ray (), which implies that the velocity of the ordinary ray is less than that of the extraordinary ray ().
