Optical Activity is a substance is said to be optically active if it can rotate the plane polarization of polarized light. It is the property (displayed by solutions of some compounds, notably many sugars) of rotating the plane of polarization of plane-polarized light.

Comment on Ernest Zinck's post “That's correct. optical activity: E, k mechanismsand E, H mechanisms. The E, k mechanisms depend essentially on the spatial variation of the electro-magnetic wave along the direction k and the E, H mechanisms on an interplay of electric polarization and magnetic induction. A more detailed mechanism for either Optical activity definition - Optically active substances or molecules rotate plane of polarization of plane polarized light either in clockwise or in anticlockwise direction.

This video will help you understand the factors influencing specific rotation such as observed rotation, g/mL, path-length, wavelength, and temperature. You will see a detailed breakdown of the equation along with a few examples to follow along. (Watch on YouTube: Optics 2. How optically active compounds rotate plane polarized light.Watch the next lesson: https://www.khanacademy.org/science/organic-chemistry/stereochemistry-topi Optical activity of a substance depends on its chirality. The direction of polarization in a plane-polarized light beam gradually rotates on its passage through such solutions. The angle of the equation of the straight line the concentration can also be determined where … Optical rotation, 'a' is the property shown by certain substances of rotating the plane of polarisation of polarised light.

You will see a detailed breakdown of the equation along with a few examples to follow along.

## In the Faraday effect, the asymmetry is due to magnetic field that is the same all over many molecules. In ordinary optical activity, the asymmetry is just molecular. Although the molecules are oriented randomly, their chirality will manifest in their interaction with light. \$\endgroup\$ – Ján Lalinský Dec 25 '13 at 20:02

The intensity of optical activity is expressed in terms of a quantity, called specific rotation, defined by an equation that relates the angle through which the plane is rotated, the length of the light path through the sample, and the density of the sample (or its concentration if it is present in a solution). A 50:50 mixture of enantiomers has no observable optical activity. Such mixtures are called racemates or racemic modifications, and are designated (±). When chiral compounds are created from achiral compounds, the products are racemic unless a single enantiomer of a chiral co-reactant or catalyst is involved in the reaction.
