A birefringence is a splitting of a ray of light into two parallel rays of perpendicular polarization by passage through an optically anistropic medium.
Birefringence is when a material is able to refract light in two slightly different directions depending upon the angle of the light coming in. Crystals if calcite can be shown to do this.
Everyone who is interested in faceting is likely to have seen the double image that is visible through a crystal of calcite. Most know that this is due to a property called 'birefringence' and that highly birefringent materials are often prone to cleavage and hard to polish.

There is no pressure in a vacuum, a vacuum is the absence of anything, there is nothing there to push. Air from a pressurized space that becomes open to a vacuum may push you into the vacuum, but the vacuum itself does nothing as it is literally nothing.
vacuum-phobia or vacuum-cleaner-phobia
first you have to determinate in witch step of the process you gett the birefringence. Usually it is in the molding of layer-0

cloaking device, they use calcite's birefringence to bend light around objects seen with the human eye.
Calcite is a natural calcium carbonate - an example of birefringence.
by rubbing the mineral on a rough hard surface
why are vacuum flasks called vacuum flask

Because it has a vacuum.
It is vacuum
A Vacuum is the absence of air. So no, there is no air in a vacuum.
