Question

which of the following lines in hydrogen spectrum is obtained corresponding to the second line of brackett series in he+ ion spectrum having same wavelength
a) first line of Lyman series
b) second line of Lyman series
c) first line of balmer series
d) second line of balmer series​

Answer 1

Answer:

first line of Lyman series

Explanation:

this is the answer

Answer 2

Answer:

option b is correct

Explanation:

In hydrogen spectrum the series of lines belong to regions are as follows:

Lyman series is in U.V. region. Balmer series is in visible region. Paschen, Brackett and Pfund series are in infrared region.

Hence, option b is correct.
