The limiting line Balmer series will have a frequency of

Options

A. (a)`32.29xx10^(15) s^(-1)`
B. (b)`3.65xx10^(14) s^(-1)`
C. (c )`-8.22xx10^(14) s^(-1)`
D. (d)`8.22xx10^(14) s^(-1)`

Answer

C

Explanation

The limiting line of Balmer series refers to the transition from `oo` to 2nd orbit
`v=3.29xx10^(15)(1/n_(1)^(2)-1/n_(2)^(2))s^(-1) (n_(1)=2, n=oo)`
`=3.29xx10^(15)xx1/4=8.22xx10^(14) s^(-1)`
