Question

the Balmer series of spectral lines of hydrogen appears in the visible region what is the lower energy level that the electron transition start from and what transition correspond to the spectral line at 399nmand 430nm respectively

Answer 1

Hydrogen spectral series:  

The emission spectrum of hydrogen is divided into a number of spectral series.  

That starts from lyman series and ends to pfund series  

That is:  

Lyman, Balmer, Paschen, Brackett and Pfund.  

The lower energy level that the electron transition start from is Lyman series that starts from n=1, where n is the lower energy level.

Transition correspond to the spectral line at 399nmand 430nm , is of balmer series that starts from n=2 and corresponds to visible region.

Answer 2

Answer:

hey hope you get it !!

Explanation:

The lower energy level that the electron transition starts from is Lyman series that starts from n=1, where n is the lower energy level.

Transition correspond to the spectral line at 399 nm and 430 nm, is of blamer series that starts from n=2 and corresponds to visible region.
