Question

Why Do We Use Polari-meter

Answer 1

The use of a Polari-meter

1. A Polari-meter is used to measure the optical rotation developed when the polarized light is passed through an optically active substance.
2. A Polari meter is an optical instrument with which one can accurately measure the angle by which the polarization of light is rotated.

Hence, the Polari-meter is used for measuring the optical rotation of the polarized light.
