• Sodium (Na) Lamp is used in a polarimeter because it gives monochromatic light and also gives high-energy output. High sensitivity and S/N ratio.
• Line spectrum i.e. gives monochromatic light of 589nm.
• A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance.
