Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials.
Optical activity is usually found in organicsubstances. For example, the sugar solution is optically active, it exhibits optical rotation on observing through the polarimeter. Other examples of optically active substances are turpentine, sodium chlorate, cinnabar, etc...
