What Is Line Spectrum ?
This Physics e learning material helps you to understand what is line spectrum. This physics animation is done with the help of top most physics teachers who have experience in online teaching.
Line spectra are sharp lines of definite wavelengths. It is the characteristic of the emitting substance. It is used to identify the gas. Atoms in the gaseous state, i.e. free excited atoms emit line spectrum. The substance in atomic state such as sodium in sodium vapour lamp, mercury in mercury vapour lamp and gases in discharge tube give line spectra.
