Question

How to determine left and right circular polarization?

Answer 1

solutions of some organic compounds have the ability to rotate the plane of polarized light . these compounds are said to be optically active, and this property of a compound is called optical activity.
optical activity of a compound is measured by an instrument called polarimeter.
an optically active compound can exist in two isometric forms, which rotate the plane of polarized light in opposite direction . these are called optical isomers. the isomers which rotate the plane of polarized light to the right is said to be dextrorotatory isomer or +ve isomer and the isomer which rotate the plane of polarized light to the left is said to be levorotatory isomer or _ve isomer
