For taking an electron around a circular path,
Work done, W = 0
On an energy level diagram of hydrogen, show by a downward or an upward arrow, a transition which results in:
(i) Emission line of Balmer series.
(ii) Emission line of Lyman series.
(iii) Absorption line of Lyman series.
Draw the energy level diagram of a hydrogen atom; and draw arrows to show transitions responsible for:
(i) Absorption lines of Lyman series.
(ii) Emission lines of Balmer series.
