## Polarization

In this article we want to consider the polarization for matters and atoms. We know that if a special ray go down to the surface of a transparent matter and if it was not polarized when it beats to the transparent matter like glass and water it will reflex to polarized way (of course it be in a special angle from water to the ray or from ray to perpendicular line to the water. Now we want to say the reason of that which why effect this event. We know that the special angle is different for different matters like glass or water or... and that's because which the (n) or refracture index for different matters is different and we easily can get the special number for different matters but to this way that we should get the angle between the refracted ray and reflected way to 90o and this subject that why we should take the angle to 90o is a experiment number. So we can get the angle with the Snell law and Brewster law. And in this article we want to consider that why the angle should be 90o (to theory way).
