Rotation of plane polarized light is measured by

A

Manometer

B

Polarimeter

C

Viscometer

D

Refractometer

Text Solution

Verified by Experts

The correct Answer is:
B
Polarimeter is an instrument used for measuring the optical rotation. It consists of two Nicol prisms, one called the polariser (near the light source) and the other called the analyser (near the eye). In between the polariser and analyser, a glass tube containing the solution of an optically active compound is placed.
