In aerosol form, sodium is applied to nuclear, electronic industries, and medical fields. The bright line at the specific wavelength corresponds to the energy difference resulting in a specific color giving off an emission spectrum. Introduction Sodium is one of the most useful ingredients in everyday life. For example, when a hydrogen atom drops from the second energy level to the first energy level, it gives off a radiation whose energy is equal to the difference of energy of both energy levels. The spectrum obtained from a sodium vapour lamp is an example of.Hence when an atom drops from higher energy level to lower energy level, it emits some amount of energy in the form of radiation of exact energy. Part 3 A spectroscope is used to study the relationship between light emitted by excited sodium atoms and the atomic energy levels of sodium. For example, sodium shows two yellow lines at the wave length 589.0nm and 589.6nm which are clearly visible.Generally the light from neon sign lamps, sodium vapor lamp and mercury vapor lamp gives line spectrum.Lines in line spectrum can be of different colors which depends on substance and temperature. In the specific case of sodium the resulting emission spectrum shall exhibit characteristic yellow lines.Such type of spectrum is termed as line spectrum. Few darker specks of blue were observed, possibly from the same substance that made the specks, when sodium was burned. These lines are not continuous but separated by dark line.Sodium is found widely in nature, and lots of substances produce these lines. What is the approximate difference in energy between the two energy levels. Sodium salts, when heated in a flame, give that flame a bright yellow color, and this color matches the two brightest lines in the emission spectrum of sodium. When atoms of any substance excited by supplying some amount of energy, they emit radiations which form bright lines in spectrum. Sodium atoms emit a spectral line with a wavelength in the yellow color, 589.6 nm.Concepts of Physics by HC Verma for JEE.IIT JEE Coaching For Foundation Classes.
