The correct answer is: When unpolarised light passes through a Nicol's prism, the emergent light is elliptically polarised
It magnitude of light vector varies periodically during it's rotation, the tip of vector traces an ellipse and light is said to be elliptically polarised. This is not in nicol prism.
