It only takes a minute to sign up. Because a sample of hydrogen contains a large number of atoms, the intensity of the various lines in a line spectrum depends on the number of atoms in each excited state. The number of these lines is an infinite continuum as it approaches a limit of 364.6 nm in the ultraviolet. As you see you should not mix $N = \text{total number of levels}$ with $n$ quantum number. At the temperature in the gas discharge tube, more atoms are in the n = 3 than the n ≥ 4 levels. Two years back my friend told me a simple formula for calculating the number of spectral lines. 4.7k VIEWS. If an atom has $N = \text{number of levels}$ then the number of transitions and therefore number of spectral lines is $N-1$. Maximum number of different spectral lines which will be obtained in visible region when in a sample of large number of H-atoms containing atoms in 2nd , 3rd and … Spectral lines carry a wealth of information on the physical properties of the medium in which they were formed.

When resolved by a spectroscope, the individual components of the radiation form images of the source (a slit through which the beam of radiation enters the device). New questions in Physics. A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. The origin of spectral lines in the hydrogen atom (Hydrogen Spectrum) can be explained on the basis of Bohr’s theory. What does it mean when an aircraft is statically stable but dynamically unstable?
