MCQ
Rotation of plane polarised light is measured by
- AManometer
- ✓Polarimeter
- CViscometer
- DRefractometer
✓
Answer
Correct option: B.
Polarimeter
b
(b) Polarimeter is an instrument used for measuring the optical rotation. It consists of two Nicol prisms, one called the polarizer (near the light source) and the other called the analyser (near the eye). In between the polarizer and analyser, a glass tube containing the solution of an optically active compound is placed.
