Calculate thewavenumberfor thelongestwavelengthtransitionin the Balmerseries of atomichydrogen

Answer»

SOLUTION :ForBalmerseries `n_(i)= 2 ` and ` n_(2)= 3 ,4,5 `
forlongestwavelengthtransitionthe isleast
Accordingto balmer
`VEC( v) =109677 ((1)/(n_(1)^(2) )-(1)/(n_(2)^(2))) cm^(-1)`
`=10967 ((9-4)/(36))`
`=109677 ((5)/(36))`
`=15232.9 cm^(-1)`
`=1.52329 xx 10^(4) cm^(-1)`
`=1.52329 xx 10^(6)m^(-1)= 1.523 xx 10^(6) m^(-1)`
