In a hydrogen atom the transition takes place from n=3 and n=2.If the Rydberg constant is 1.09*10^7 metre^-1The wavelength of the emitted radiation is?
According to Rydberg formula,
(m-) = 1.09 107
= wave number
n1 = 3
n2 = 2
RH (Rydberg constant ) = 1.09107 m-1
=
=
= - 0.151107 m-1
It is an emission spectra , hence is negative.
=
= 6.62210-7 m
Hence, wavelength of emitted radiation is 6.62210-7 m.
