What is the wavelength of H line?
656.28 nm
H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air and 656.46 nm in vacuum; it occurs when a hydrogen electron falls from its third to second lowest energy level.
How do you find the wavelength of hydrogen spectrum?
since the electron is de-exited from 1st excited state (i.e n=2) to ground state (i.e n=1) for the first line of the Lyman series. Hence the wavelength of the first line in the Lyman series of the hydrogen spectrum is λ=121.6nm .

What is the longest wavelength of hydrogen?
656 nm
According to the calculations, the longest wavelength of the electromagnetic radiation emitted by the hydrogen atom is 656 nm which is produced by the transition from n=3 to n=2.
Why does hydrogen spectrum have 4 lines?
Although hydrogen has only one electron, it contains many energy levels. When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels. Those photons appear as lines.
Why does Hydrogen spectrum have 4 lines?
Why does hydrogen only have four spectral lines?
1 Answer. when a hydrogen atom, having different energy levels absorbs energy the only electron can go any of the energy levels & while radiating different spectral lines observed.
What is the wavelength of first line of Balmer series?
The first line of the Balmer series in the hydrogen spectrum has a wavelength of 6564˚A.
What is Max wavelength of Balmer series?
