Draw the diagram of Hydrogen spectrum.

Bohr.s theory explains that when Hydrogen-like particles are excited, their electrons are shifted higher energy orbits. As such a state of atom is not stable, electrons return to lower energy orbits releasing quantum of energy. Thus different spectral lines are formed. The wave number of spectral line is given by bar(v) = (2pi^(2)me^(4)z^(2))/(c h^(3))[(1)/(n_(1)^(2)-(1)/(n_(2)^(2)))] For a hydrogen -like particle, ionization energy is 122.4 eV. Then what is the wave number of series limit spectral line of the particle of paschen seres (R = rydberg.s constant)

The Lyman series of hydrogen spectrum lies in the ultraviolet region. Why?

Balmer gave an equation for wavelength of visible region of H-spectrum as barv =(n^2 - 4)/(Kn^2) where n = principal quantum number of energy level, K = constant terms.of R (Rydberg constant). The value of K in terms of R is:

Who proposed the spectrum of hydrogen atom ?

(A) In the Balmer series of hydrogen spectrum as wavelength increases the spectral lines becomes closer. (R) For higher orbits energy gap between them decreases.

The observed wavelengths in the line spectrum of hydrogen atom were first expressed in terms of a series by Johann Jakob Balmer, a Swiss teacher. Balmer's empirical formula is (1)/(lambda) = R_(H)[(1)/(2^(2)) - (1)/(n^(2))] = n = 3, 4,5… R_(H) = 109678 cm^(-1) is the Rydberg constant. Niels Bohr derived this expression theoretically in 1913. The formula is a generalised to any on electron atom/ion. The wavelength of first line of Balmer spectrum of hydrogen will be :

The first spectral line in the Pfund series of Hydrogen spectrum is given by (R_(H)=" Rydberg constant")

The wavelength of the first member of the Balmer series in hydrogen spectrum is x Å. Then the wave length (in Å) of the first member of Lyman series in the same spectrum is
