When an electron in a hydrogen atom undergoes the transition from the energy level. The wavelength is 97.3 nm.
What is wavelength?
The separation between similar points in successive waves of a waveform signal that have traveled across space or along a wire.
1 / λ = -1.097 x 107 m-1 ( 1/nf2 - 1/ni2 )
λ = wavelength in m
nf = final energy level = 1
ni = initial energy level = 7
1 / λ = -1.097 x 107 m-1 (1/16 - 1) = 1.097 x 107 m-1 (-0.9375)
1 / λ = 1.028 x 107 m-1
λ = 9.73x10-8 m = 97.3 nm
Thus, the wavelength, in nanometers, of the spectral line is 97.3 nm.
