Optical activity can be explained on the basis of the simple assumption that the speed of propagation for right circularly polarized light in the medium is different from that of left circularly polarized light. To show this, it will be convenient to use the Jones vector notation of Section 2.5. Let nR and nL denote, respectively, the indices of refraction of the medium for right and left circularly polarized light. The corresponding wavenumbers are kR = nRω/c and kL = nLω/c, and the expressions

represent the two kinds of wave in the medium.

Now suppose that a beam of linearly polarized light travels a distance l through the medium. Let the initial polarization be in the horizontal direction. The initial Jones vector, separated into right and left circular components, is
