Question

Calculate the wavenumber for the first line in brackett series

Answer 1

Answer:

2.45*10^5 m^-1

Explanation:

wave number for 1st brackett line = 1.09678*10^7(1/4^2 - 1/5^2)

It lies in IR region

Brackett series of lines are observed when any electron jumps back to 4 shell from any higher energy level
