The atomic spectrum should be an absorption line spectrum. It is also used to prevent malaria and in combination with quinine, to treat malaria. Absorption spectrum is like the photographic negative of an emission spectrum. When some volatile salt is placed in the bunsen flame or an electric discharge is passed through a gas at low pressure, light is emitted. The statements given below are incorrect.

NEET. Such spectra are called line spectra or atomic spectra. Hydrogen Spectrum : If an electric discharge is passed through hydrogen gas is taken in a discharge tube under low pressure, and the emitted radiation is analysed with the help of spectrograph, it is found to consist of a series of sharp lines in the UV, visible and IR regions. Sodium always gives two yellow lines. Spectrum. The branch of science dealing with the study of spectra is called spectroscopy. Biology.
