    A beam of unpolarized light passes through a tourmaline crystal A and then it passes through a second tourmaline crystal B oriented so that its principal plane is parallel to that of A. The intensity of emergent light is I0I_0. Now B is rotated by 45∘45^\circ about the ray. The emergent light will have intensity (cos⁡45∘=12\cos45^\circ=\frac{1}{\sqrt{2}})
