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
Why do the Balmer lines of hydrogen exhibit a phenomenon where they get closer together as you move towards shorter wavelengths?
The Balmer lines of hydrogen exhibit a phenomenon where they get closer together as you move towards shorter wavelengths because of the energy levels of the hydrogen atom. As the electron transitions from higher to lower energy levels, the wavelengths of light emitted become shorter, causing the lines to converge.
Why are the hydrogen Balmer lines strong in the spectra of medium temperature stars and weak in the spectra of hot and cool stars?
Balmer lines are produced by colliding hydrogen atoms with electrons excited to 2nd energy level. Cool stars don't have enough collision to excite the electrons, hot stars have too much collision and excite the electrons beyond 2nd energy level.
Why do Lyman transitions produce ultraviolet photons while the Balmer transitions produce visible light photons?
The Lyman series is the group of energies corresponding to the transitionsof an electron between the "ground state" ... the lowest energy level ... andany other energy level that an electron can have in a hydrogen atom.The Balmer series is the group of energies corresponding to the transitionsbetween the second energy level in the hydrogen atom and any other one(except the ground state).But the energy difference between the ground state and the second level inthe hydrogen atom is about four times the difference between the second leveland any higher one, so it's pretty clear that any line in the Lyman series ought tohave substantially more energy than any line in the Balmer series.And that's a fact. The shortest wavelength in the Balmer series is 410 nm ...right there in violet light ... whereas the shortest wavelength in the Lymanseries is 122 nm, almost 2 octaves above the blue end of the visible spectrum,and well into the ultraviolet.Similarly . . .The Paschen series (transitions to/from the 3rd energy level),the Brackett series (transitions to/from the 4th energy level), andthe Pfund series (transitions to/from the 5th energy level)are groups of lines at longer and longer wavelengths, extending through the infraredand down into the short microwave wavelengths.The lowest-frequency/longest-wavelength transition associated with thehydrogen atom is the "flip" transition of the electron from one spin-orientation to the other. That's the so-called "Hydrogen-alpha" line at roughly1420 MHz / 21 cm. Wherever Hydrogen exists, electrons are flipping, andeither absorbing or emitting "H-α" radiation.For receivers capable of tuning 1420 MHz (no problem), the universe is alive with itin every direction. And if you have the opportunity to examine a chart of frequencyallocations, you'll notice that this frequency (and the band about 13 MHz to either side)is allocated for "Astronomy, Space Research, and Earth Exploration Satellites" (lookingaway from space !).
What light contains all the colors of the rainbow?
It's "white light". When all colours of the rainbow are combined in their purest form (light), they create white light. All colours of the rainbow can be derived from the colours red, green and blue. These 3 colours are known as the RGB colour model (Red, Green, Blue). When these three colours are combined in their purest form, they also form white light
What is the maximum wavelength of balmer series?
The Balmer series is a series of spectral lines in the hydrogen spectrum that corresponds to transitions from energy levels n > 2 to the n=2 level. The longest wavelength in the Balmer series corresponds to the transition from n = ∞ to n = 2, known as the Balmer limit, which is approximately 656.3 nm.
What is the name of the visible series in the hydrogen spectrum?
I believe it to be the Balmer Series.
In hydrogen spectrumwhat is the ratio of first line of Lyman series to the first line of balmer series?
The ratio of the first line of the Lyman series to the first line of the Balmer series in the hydrogen spectrum is 1:5.
What is the ratio of the wave length of last line of balmer and Lehman series?
The ratio of the wavelengths of the last line in the Balmer series to the last line in the Lyman series is 1:5. The Balmer series is associated with transitions to the n=2 energy level, while the Lyman series is associated with transitions to the n=1 energy level in the hydrogen atom.
What is the shortest wavelength radiation in balmer series?
The shortest wavelength radiation in the Balmer series is the transition from the n=3 energy level to the n=2 energy level, which corresponds to the Balmer alpha line at 656.3 nm in the visible 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.
The visible part of the electromagnetic spectrum falls between?
The Balmer Series
What is the balmer spectrum?
The Balmer series is a set of spectral lines in the visible region of the electromagnetic spectrum of hydrogen. It consists of four lines in the visible light spectrum resulting from transitions in hydrogen's electron shell to the second energy level. The Balmer series is significant in understanding atomic structure and spectroscopy.
Is Balmer series only present in hydrogen atom?
No, the Balmer series is observed in hydrogen-like atoms, which have one electron orbiting a nucleus. It consists of the spectral lines produced when the electron transitions from higher energy levels to the second energy level. Other atoms with similar electron configurations can also exhibit Balmer-like series in their spectra.
What is ratio of maximum and minimum wavelength of balmer series?
5:9 ,i am not sure (;
Why it is not possible to observe the n7 to n2 transition in the Balmer Series?
The Balmer Series describes the transitions of electrons in a hydrogen atom from higher energy levels (n ≥ 3) down to the n = 2 level, resulting in visible light emissions. The n = 7 to n = 2 transition falls within the ultraviolet range, which is not part of the visible spectrum typically associated with the Balmer Series. Consequently, while such transitions can occur, they cannot be observed as part of the Balmer Series since they emit wavelengths that are outside the visible range. Thus, the n = 7 to n = 2 transition is not considered part of the series.
What are the wavelengths of the first lines in the Balmer series?
The first lines in the Balmer series of hydrogen correspond to transitions to the n=2 energy level. The wavelengths of these lines are 656.3 nm (Hα), 486.1 nm (Hβ), 434.0 nm (Hγ), and 410.2 nm (Hδ).
