In theory, hydrogen has infinitely many spectral lines. The "Balmer series" has four lines in the visible spectrum; additional lines are in the ultraviolet. Other "series" have other lines - it seems that all of them are either in the ultraviolet or infrared. For more information, read the Wikipedia article on "Hydrogen spectrum". The reason there are four VISIBLE lines is basically chance - an excited hydrogen atom emits light at certain frequencies (which can be calculated, see the article for more details); our eyes see a certain range of electromagnetic waves that happens to include four of those lines.
What else can I help you with?
How many different lines can be drawn if each line contains abcde at least two of these points?
The answer will depend on the relative positions of the points.
What is the slope of the line that contains the points -4 3?
(-4, 3) is a single point. An infinite number of lines, all with different slopes, can contain it.
What are slanting lines?
Slanting lines are lines that are straight but lean in another direction.
What are two intersecting lines called?
Either perpendicular lines if the lines create 90o angles or intersecting lines.
Line that have Slopes that have negative reciprocals are ---- to each other?
Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.
What is the difference between sunlight produced spectrum and hydrogen gas produced spectrum?
Sunlight produced spectrum is continuous and contains a broad range of wavelengths, while hydrogen gas produced spectrum consists of discrete lines at specific wavelengths due to the unique energy levels of hydrogen atoms. Sunlight spectrum is continuous due to the various processes that produce light, whereas hydrogen gas spectrum is a result of the energy levels of hydrogen atoms emitting photons of specific wavelengths.
Does the helium spectrum have twice as many lines as the hydrogen spectrum?
No. In vacuum(i.e.no continuum lowering), both have an infinite number of lines in the spectrum, hence the question makes no sense.
Which element did Bohr study the line emission spectrum of?
Niels Bohr studied the emission lines of Hydrogen.
Who developed an equation used to predict the lines in the emission spectrum of hydrogen?
Rydberg
Why the distances between the lines for the hydrogen spectrum decreases with the decrease in wavelength?
The distances between lines in the hydrogen spectrum decrease with decreasing wavelength because the energy levels in hydrogen are quantized, meaning they can only exist at certain discrete values. As the wavelength decreases, the energy difference between adjacent levels also decreases, resulting in lines being closer together in the spectrum.
Why hydrogen gas have large no of lines?
The fraunhofer (absorption) and excitation spectrum of hydrogen has lines for each energy level that electrons can pass from one excitation stat to another.
What does it mean when a star has no hydrogen lines in its spectrum?
When a star has no hydrogen lines in its spectrum, it means that the star is likely depleted of hydrogen in its outer layers. This could indicate that the star has evolved past the main sequence phase where hydrogen fusion occurs, and is now in a later stage of its life cycle.
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.
Can The optical spectrum of hydrogen and all other elements consist of a set of discrete lines?
true
How do you think the lines you observed in the hydrogen emission spectrum relate to the energy of the electrons in a hudrogen atom?

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 produced by hydrogen are primarily the Paschen series. These lines are transitions of electrons in hydrogen atoms from higher energy levels to the third energy level (n=3). Typical Paschen series lines in the infrared include Paschen-alpha at 1.875 μm and Paschen-beta at 1.282 μm.
