Question

Paschen series of atomic spectrum of hydrogen gas lies in:
(a) Infrared region
(b) Ultraviolet region
(c) Visible region
(d) Partly in ultraviolet and partly in visible region​

Answer 1

Answer:

ultraviolet region

I hope this help you

Answer 2

Paschen series of atomic spectrum of hydrogen gas lies in infrared region

explaination:    

• SO,the given question answer must be (A).  

• the lines in spectrum is due to the excitation of electrons from one energy level to another energy level

• the  lines in the spectrum of the hydrogen atom which are having  transitions between the states with principal quantum number n=3 and successive higher states called paschen series.
