State Both's quantization condition of angular momentum. Calculate the shortest wavelegth of the Bracket series and state to which part of the electromagnetic spectrum does it belog.

Explanation

Bohr's quatization condition : According to Bohr, an electron can revolve only in certain discrete, non-radiation orbits for which the total angular momentum of the revolving eletron is an intergal multiplde of `h/(2pi)` where h is the Plank's constant
`"L = mvr ="(ng)/(2pi)`
`"Braket Series "1/lamda=R[1/4^(2)-1/n^(2)]`
For shortest wave length `n=oorArr1/n^(2)=0`
`1/lamda=R/16`
`lamda=16/R=16/(1.097xx10^(7))=14.58523xx10^(-7)m=14585.23xx10^(-10)m=14585.230Å`
It belong to infrared region.
