Question

The limiting line in Brackett series corresponds to
a. n₁ = 4 , n₂ = 5
b. n₁ = 2 , n₂ = 10
c. n₁ = 2 , n₂ = ∞
d. n₁ = 4 , n₂ = ∞

Answer 1

Answer:

Answer is option (d)

Explanation:

As the first line in Brackett series

n1=4 and n2=5

The limiting line of Brackett Series is defined as when the electron descends from infinity to 4th shell

So correct answer is option d
