What are the wavelengths of the lines in the hydrogen emission spectrum?
The four spectral lines of the Balmer series that fall in the visible range are: 656.3 nm . . . . red 486.1 nm . . . . cyan 434.1 nm . . . . blue 410.2 nm . . . . violet There are four more lines in the Balmer series ... all in the ultraviolet ... and at least thirty-six observable lines altogether from the hydrogen atom.
If we would see a fifth line in the Balmer series emission spectrum. Calculate the wavelength associated with the fifth line?
m lmn ?,
What color is the wavelength of light in the Balmer series that results from the transition of an electron to N equals 2?
There are 4 Balmer lines with wavelengths in the visible region. They are red, aqua and two shades of violet. Other Balmer lines are in the ultraviolet. The red line corresponds to the transition from n = 3 to n = 2, the subsequent ones are from the 4, 5 and 6 levels to n = 2.
What is Schrodinger's equation?
The Schrödinger wave equation shows the interactions between particles and potential fields (i.e., electrons within atoms) by describing the behavior of such a system. Elaborating a little more, a particle is described by what is called a wavefunction. This wavefunction has a space (x,y,z) and time (t) dependency and is continuous, finite and single valued. Therefore the Schrödinger wave partial differential equation shows how the wavefunction of a system behaves over time.

What is the name of the third series in the spectrum of hydrogen?
In ascending order of the lower energy state involved in the transition, the first six families of lines in the hydrogen spectrum are: Lyman series Balmer series Paschen series Brackett series Pfund series Humphreys series
What is the name of the visible series in the hydrogen spectrum?
I believe it to be the Balmer Series.
What are the absorption lines in the infrared portion of the spectrum of a star that are produced by hyrdrogen are from?
The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.
What has the author Percy Lowe written?
Percy Lowe has written: 'Structure of the Balmer series lines in the spectrum of hydrogen'
What is the Balmer Series?
The Balmer series is a section of the hydrogen atomic emission line spectrum. They show the wavelengths of light emitted when electrons transition back to the n = 2 quantum level.
How many shells in a Bohr Atomic Model?
Bohr model consists only one shell.(a hydrogen atom shell) But shell can be increased by exciting the atom. When the electron comes to its shell it loses energy,therefore,different types of regions have been observed i.e,(Lyman,Balmer,Paschen,Bracket and Pfund)
What is the line spectrum of the hydrogen atom?
All in nM (nano metre, in vacuo): The Balmer series: (up to 3 eV energy) 397 410 434 486 656
The visible part of the electromagnetic spectrum falls between?
The Balmer Series
What is the formula parallel to rydberg's formula?
The formula parallel to Rydberg's formula used in Bohr's theory of the emission spectrum of the hydrogen atom is the Balmer Series. See related link for more information.
Is hydrogen red in the electromagnetic spectrum?
There are two very narrowly separated lines in the excitation spectrum of hydrogen at about 656 nm, which is in the red region of the spectrum. The energy corresponds to a transition from n=3 to n=2 (Balmer series). These are far and away the most intense lines in the visible region of the spectrum, but there is also a line in the blue-green region, and several in the violet part. The overall color of a hydrogen lamp (analogous to a neon lamp, but with hydrogen instead) is a sort of fuchsia or magenta color. See the link in the "related links" section for a picture.
Is Balmer series only present in hydrogen atom?
Balmer series just represents the visible radiations region and it is present in the spectra of every element. It is just the case that we study only hydrogen atom.
Why are the hydrogen Balmer lines strong in the spectra of medium-temperature stars and weak in the spectra of hot and cool stars?
They are like this due to the fact that most hydrogen atoms are ionized which makes a weaker balmer line. The strength of the Balmer line is sensitive to temperature so that's why it occurs more in the middle. The hot end of the hydrogen is low Balmer line due to them being in the ground state. Hope that's answers it =] -CRS
