Wavenumber of the second line belonging to Balmer series in hydrogen emission spectrum can be determined using Rydberg equation as follows,
For the second line belonging to Balmer series the transition will be from n = 4 to n = 2.
1 λ = R [ 1 n final 2 1 n initial 2 ] = 1.097 × 10 7 m 1 [ 1 2 2 1 4 2 ] = 2.057 × 10 6 m 1
Wavelength of the second line belonging to Balmer series in hydrogen emission spectrum can be determined as follows,
Wavelength, λ = 1 2.057 × 10 6 m 1 = 4.85 × 10 7 m
Hence, wavelength of the second line belonging to balmer series is 4.86 × 10 7 m
