In a certain electronic transition from the quantum level, 'n' to the ground state in atomic hydrogen in one or more steps, no line belonging to the Bracket series is observed. What wave number may be observed in the Balmer series ? (R = Rydberg Constant)

Options

A. `(8R)/(9),(5R)/(36)`
B. `(3R)/(16),(8R)/(9)`
C. `(5R)/(36) , (3R)/(16)`
D. `(3R)/(4),(3R)/(16)`

Answer

C

Explanation

No line in brackett series `implies ` `n_2 ne 4` and `n_2 lt 4`
