A mixture contains {H} atom and LiP* ions. Electron is H-atom is in 3^{\text{rd }} excited state and e in Li { }^{2 *} is in 5^{\text{th }} excited state. Then which is lare true about the spectral lines observed for the mixture

emitted radiation will contain 21 lines

emitted radiation will contain 19 lines

more than 10 lines are in u.v range

if sample contains only H atom then emission spectrum contains two visible lines
