کسی کمپاؤنڈ کی آپٹیکل سرگرمی کی پیمائش کے لئے مندرجہ ذیل میں سے کون سا آلات استعمال ہوسکتے ہیں؟

Polarimeter

Spectrophotometer

Calorimeter

None of these

A polarimeter measures the optical activity of a compound by analyzing the rotation of plane-polarized light.

Optically active compounds, like chiral molecules, rotate light either clockwise (dextrorotatory) or counterclockwise (levorotatory).
