This action cannot be undone. This will permanently delete All Practiced Questions. The frequency of the series limit of the Balmer series of hydrogen atoms in terms of Rydberg constant R and velocity of light C is:.

A sequence of absorption or emission lines in the visible part of the spectrum, due to hydrogen; also known as Balmer lines. Balmer absorption lines are caused by jumps of electrons from the second energy level to higher levels, and emission lines when the electrons drop back to the second energy level. They are named after the Swiss mathematician Johann Jakob Balmer — See also hydrogen spectrum. From: Balmer series in A Dictionary of Astronomy ».

The Balmer series , or Balmer lines in atomic physics , is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is calculated using the Balmer formula, an empirical equation discovered by Johann Balmer in The visible spectrum of light from hydrogen displays four wavelengths , nm , nm, nm, and nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum number n equals 2. The series continues with an infinite number of lines whose wavelengths asymptotically approach the limit of After Balmer's discovery, five other hydrogen spectral series were discovered, corresponding to electrons transitioning to values of n other than two. As the first spectral lines associated with this series are located in the visible part of the electromagnetic spectrum , these lines are historically referred to as "H-alpha", "H-beta", "H-gamma", and so on, where H is the element hydrogen. Although physicists were aware of atomic emissions before , they lacked a tool to accurately predict where the spectral lines should appear.

The series is named after its discoverer, Theodore Lyman. The greater the difference in the principal quantum numbers, the higher the energy of the electromagnetic emission. The first line in the spectrum of the Lyman series was discovered in by physicist Theodore Lyman , who was studying the ultraviolet spectrum of electrically excited hydrogen gas. The rest of the lines of the spectrum all in the ultraviolet were discovered by Lyman from The spectrum of radiation emitted by hydrogen is non-continuous or discrete. Here is an illustration of the first series of hydrogen emission lines:. Historically, explaining the nature of the hydrogen spectrum was a considerable problem in physics.

A hydrogen discharge tube is a slim tube containing hydrogen gas at low pressure with an electrode at each end. If a high voltage volts is applied, the tube lights up with a bright pink glow. If the light is passed through a prism or diffraction grating, it is split into its various colors. This is a small part of the hydrogen emission spectrum. Most of the spectrum is invisible to the eye because it is either in the infrared or the ultraviolet region of the electromagnetic spectrum. The photograph shows part of a hydrogen discharge tube on the left, and the three most apparent lines in the visible part of the spectrum on the right. Ignore the "smearing," particularly to the left of the red line. This is caused by flaws in the way the photograph was taken. See note below. The hydrogen spectrum is complex, comprising more than the three lines visible to the naked eye.

According to Bohr's theory, the moment of momentum of an electron revolving in second orbit of hydrogen atom will be: 1. In the following reaction. Cancel Save. Sign in with your library card Please enter your library card number. In the spectra of most spiral and irregular galaxies, active galactic nuclei , H II regions and planetary nebulae , the Balmer lines are emission lines. Don't have an account? They are named after the Swiss mathematician Johann Jakob Balmer — The shortest wavelength is given by:.

The emission spectrum of atomic hydrogen has been divided into a number of spectral series , with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom.

An electtron and a photon have same wavelength. Because the Balmer lines are commonly seen in the spectra of various objects, they are often used to determine radial velocities due to doppler shifting of the Balmer lines. Balmer's equation inspired the Rydberg equation as a generalization of it, and this in turn led physicists to find the Lyman , Paschen , and Brackett series , which predicted other spectral lines of hydrogen found outside the visible spectrum. An electron jumps from the 3rd orbit to the ground orbit in the hydrog H-epsilon is separated by 0. The spectral classification of stars, which is primarily a determination of surface temperature, is based on the relative strength of spectral lines, and the Balmer series in particular is very important.
