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

Due to variation in refractive indices, just one ray will pass through the crystal in a slower rate than another ray. Quite simply, the velocity in the slower ray will likely be retarded with regard to your more quickly ray. This retardation worth (the relative retardation) can be quantitatively identified making use of the next equation:If the ele
