can an ordinary tourmaline crystal polarise light?
is it necessary that it should be cut parallel to its optic axis?
Not necessary. When the thickness is high ordinary ray of light is absorbed by the crystal and only the extra-ordinary light comes out.
If cut we can identify the position of crystal to produce the polaraised light.
