Explanation:
Detailed explanation-1: -Polarimetry is the measurement of optical rotation of substances by using a polarimeter. A polarimeter is an instrument which measures the angle of rotation by passing polarized light through an optically active (chiral) substance.
Detailed explanation-2: -Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter. A simple polarimeter consists of a light source, polarising lens, sample tube and analysing lens.
