Why the distance between the emission lines of hydrogen decreases as we move to the right?
This is explained in the Bohr model by the realization that the electron orbits are not equally spaced. As the energy increases further and further from the nucleus, the spacing between the levels gets smaller and smaller.
Why did the spectral lines get closer and closer together as you approach the violet end of the spectrum?
Q1: Why do the spectral lines in the Balmer series get closer together going from red to violet? a) the lines get closer together because the prism separates the light on a logarithmic scale.
What is the relationship between the de Broglie wavelength and the mass of the moving particle?
Louis de Broglie showed that the wavelength of a particle is equal to Planck’s constant divided by the mass times the velocity of the particle. The electron in Bohr’s circular orbits could thus be described as a standing wave, one that does not move through space.
Why does hydrogen have multiple spectral lines?
Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released… hence, mono-electronic hydrogen has many spectral lines.
Which wavelength of the band on the hydrogen emission line spectrum has the most energy?
The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm.
Why does hydrogen atom produce so many spectral lines even though it contains one electron?
What causes the lines in the spectrum of a hydrogen atom?
The lines in the spectrum of the hydrogen atom are caused by an electron moving from a higher energy level to a lower energy level. Light is emitted in that process. The shorter the wavelength of the light emitted, the greater its energy.
Why do spectral lines get closer together as the wavelength decreases?
Shorter wavelength light has more energy, of course. The electron energy levels get closer together as the energy levels get higher. Hence the differences between the energy levels become smaller at higher energy levels. So the spectral lines (in any particular series) get closer together as wavelength decreases.
Why do spectral lines appear closer in the high-energy regime?
To conclude, the spectral lines appear closer in the high-energy regime because of the hyperbolic dependence of the spectral wavelength on the emitted photon energy. I hope this helps. The lines in the spectrum of the hydrogen atom are caused by an electron moving from a higher energy level to a lower energy level.
What is the Balmer series of the hydrogen emission spectrum?
This series of the hydrogen emission spectrum is known as the Balmer series. This is the only series of lines in the electromagnetic spectrum that lies in the visible region.
