Vedclass · Answer

(B) When hydrogen gas is heated or subjected to an electric discharge (incandescent source),the electrons in the hydrogen atoms absorb energy and get excited to higher energy levels. As these electrons return to lower energy states,they emit electromagnetic radiation in the form of discrete wavelengths. Because hydrogen is a simple atomic gas,these emissions appear as distinct,sharp lines rather than continuous bands. Therefore,the hydrogen spectrum is a line spectrum in emission.

The hydrogen spectrum from an incandescent source of hydrogen is:
