There are following transition series in case of hydrogen spectrum
a) Lyman series : it is when electron transit from n1= 2 to n2= 3,4 ,5 .....
It falls in UV region
b) Balmer series : it is when electron transit from n1= 2 to n2= 3,4 ,5 .....
It falls in visible region
c) pachen series : it is when electron transit from n1= 3 to n2= 4 ,5 .....
It falls in IR band
d) Brackett : it is when electron transit from n1= 4 to n2= 5,6,7 .....
It falls in Ir band
and so on
As asked we have assign ultraviolet absorption : n1 = 1 to n1= 2,3,4,5
ultraviolet emission: n2 = 2,3,4,5..... to n1= 1
