Q. Out of the following statements which is not correct
A) When unpolarised light passes through a Nicol prism, the emergent light is elliptically polarised
B) Nicol prism works on the principle of double refraction and total internal reflection
C) Nicol prism can be used to produce and analyse polarized light
D) Calcite and Quartz are both doubly refracting crystals
Explanation
(a) If magnitude of light vector varies periodically during it’s rotation, the tip of vector traces an ellipse and light is said to be elliptically polarized. This does not happen prism
