In hydrogen spectrum the shortest wavelength in the Balmer series is . The shortest wavelength in the Bracket series is:
Multiple Choice Options
- A 4 _
- B 9 _
- C 16 _
- D 2 _
Step-by-Step Verified Solution
Shortest wavelength in Balmer series when transition of e _ from � to n = 2
_ 1 _ = Rz 2 [ 1 2 2 _ 1 � 2 ]
1 _ = R 4 .... (1)
Shortest wavelength is Bracket series when transition of e _ from � to n = 4
1 _ _ = R ( 1 ) 2 [ 1 4 2 _ 1 � 2 ] _ 1 _ _ = R 16 ..... (2)
Eq. (1) / Eq. (2)
_ _ _ = R 4 _ 16 R _ _ _ = 4 _
