HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD BIREFRINGENT CRYSTAL

Because of the variance in refractive indices, a person ray will go through the crystal in a slower price than the opposite ray. Basically, the velocity of the slower ray will likely be retarded with regard to the more quickly ray. This retardation worth (the relative retardation) might be quantitatively decided working with the next equation:Be at
