Why Na lamp is used in a polarimeter ?<\/h2>\r\n\r\n\r\n\r\n
\r\n
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.<\/li>\r\n
Line spectrum i.e. gives monochromatic light of 589nm.<\/li>\r\n
A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<\/figure>\r\n
