As Hydrogen has single atom , its spectrum is simple.When hydrogen gas is heated or subjectedto electric discharge at low pressure,the molecules if hydrogen are split into atoms.Electrons in these atoms absorb different quanta energy and get excited to different energy levels.Thus formed excited hydrogen atoms are unstable.So electrons will come to low energy levels in either single step or several steps. In each transition energy is released and it appears as libe in hydrogen spectrum....
