The core principle establishes that linearly polarized light is a superposition of counter-propagating circularly polarized components with opposite handedness (left- and right-handed). When passing through a medium containing chiral molecules, such as sucrose solution, these two components experience distinct indices of refraction due to the lack of mirror symmetry in their interaction with the asymmetric molecular environment. The resulting differential phase accumulation between the orthogonal circular components rotates the net linear polarization vector upon propagation, demonstrating that optical activity is fundamentally governed by the coupling between electromagnetic wave dynamics and material chirality.
