It rotates due to an external magnetic field in the Faraday effect.
The null intensity and Kent-Lawson methods are used to compute this quantity. A ratio of two forms of this quantity is represented as a complex number with amplitude "tan psi" and phase "delta." One method to parametrize this quantity is a set of 4X4 matrices which generically has eight non-zero elements. In a formalism analogous to the Stern-Gerlach experiment, the spin kets are replaced by R and L basis vectors for this quantity. This quantity, which can be visualized on a(*) Poincaré sphere, is transformed by the Mueller or Jones matrices, which decompose it into three directions by the Stokes parameters. Waveplates delay one component of this quantity in a process called retardance. It rotates due to an external magnetic field in the Faraday effect. For 10 points, name this quantity which can be circular or linear and represents the direction in which an electromagnetic wave oscillates.
