Calculate the wave number for the longest wavelength transition in the Balmer series of atomic hydrogen

Text Solution

Verified by Experts

For Balmer series `n_(i) = 2 ` and ` n_(2) = 3 ,4 ,5 `
for longest wavelength transition the is least
According to 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)`
