How does the Polarimeter work? | MCAT Chemistry
This video talks about how the polarimeter works. A polarimeter is an optical instrument used to measure the rotation of polarized light caused by chiral substances. Chirality refers to molecules that are non-superimposable mirror images of each other, like left and right hands.
This video will help you learn the basics and foundational knowledge needed to ace your exams!

Glad it helped!
Is it the analyzer that helps us identify the plane of rotation of the light, that is whether clockwise or anticlockwise, or some dark room, or what?

Yes, the analyzer plays a crucial role in identifying the plane of rotation of light, whether it is clockwise or anticlockwise. In a typical experimental setup, the analyzer is positioned after the sample or substance that is being tested for optical activity. By rotating the analyzer and observing changes in the intensity of transmitted light, one can determine the direction of rotation (clockwise or anticlockwise) induced by the sample. This process is often carried out in a controlled environment, such as a dark room, to minimize external light interference and ensure accurate measurements. Hope this helps!
