Answer 2

Hydrogen spectrum : -

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ when hydrogen gas is subjected to scilent electric discharge. The electron of hydrogen atom gets excited to various excited levels and de-excited to form various spectral lines in varoius regions is called Hydrogen spectrum.

Hydrogen spectrum contains 5 series of lines :-

Lyman series : -

when an electron jumps from higher energy level to the first orbit is known as Lymann series. Also it is observed in UV region.

Balmer series : -

when an electron jumps from higher energy level to the second orbit is known as Balmer series. Also it is observed in Visible region .

Paschen series : -

when an Electron jumps from higher energy level to the third orbit is known as Paschen series . Also it is Observed in Near IR region .

Bracket series : -

when an Electron jumps from higher energy level to the fourth orbit is known as Bracket series . Also it Is observed in IR region .

Pfund series : -

when an Electron jumps from higher energy level to the fifth orbit is known as Pfund series . Also observed in Far IR region .
