For two Bohr orbits & which follow the relationships,
( - ) = 33 and ( - ) = 3.
If an electron makes transition from to directly then :
Options:(select one or more)
Answer:
A, C, D
Solution:
n2 + n1 = 33/3 = 11 and n2 - n1 = 3, so n2 = 7 and n1 = 4: transition 7 → 4.
(A) n1 = 4 is the Brackett series: true.
(B) Shortest wavelength of Brackett is ∞→4: false.
(C) Brackett wavelengths in decreasing order: 5→4, 6→4, 7→4. So 7→4 is the third longest: true.
(D) A single direct transition gives one line: true.
Answer: (A), (C), (D).
