There are an infinite number of transitions, but only 4 of these transitions emit energy in the visible region of the spectrum. That's what our teacher told us。
Short Answer: These four lines are utterly specific for Hydrogen, just like a fingerprint.
Answer 1The wavelengths contained in a light source...________________________________________Answer 2It is a spectrum of energy that is mainly concentrated at particular a wavelength. It is produced by excited atoms and ions as they retreat into a lower energy level.
it has four covalent bonds and four hydrogen atoms in it you dumbo
No, it contains two: hydrogen and nitrogen, It does however contain four different atoms: one of nitrogen and three of hydrogen.
Hydrogen peroxide (H2O2) contains two atoms of hydrogen and two atoms of oxygen for a total of four atoms.
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.
The hydrogen emission spectrum consists of several distinct lines corresponding to transitions of electrons between energy levels. The wavelengths of the lines range from ultraviolet to infrared, with prominent lines at 656.3 nm (red), 486.1 nm (blue), and 434.0 nm (violet). Each line corresponds to a specific energy transition in the hydrogen atom.

Hydrogen breaks down into four colors. Violet at 410 nm, blued/violet at 434 nm blue/green at 464.4 nm and red of 656.2 nm.

NO. It produces four lines with wide difference in wavelengths. So it is not a monochromatic just as sodium vapour lamp
A stanza of four lines is called a quatrain.
A quatrain is, in poetry, a specific type of poem. There are not many rules to follow, and writing a quatrain is fairly simple. The quatrain contains just four lines. That's it and that's all the rules for writing a quatrain.
The "Balmer Series" includes the visible spectrum of light from hydrogen ... fourwavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissionsof photons by electrons in excited states transitioning to the quantum level describedby the principal quantum number n equals 2. (There are also a number of ultravioletBalmer lines with wavelengths shorter than 400 nm.)Of the four visible Balmer lines, the one with the longest wavelength ... 656 nm ...is the one with the lowest energy per photon. It appears quite red.
They are four lines that coincide pairwise in at least four distinct points.
A square has exactly four lines of symmetry.
If you think about it youwill know.But a Square has four lines of symmetry.
