Photon emissions from hydrogen

In summary, photon emissions from hydrogen occur when an electron transitions from a higher energy level to a lower one, releasing energy in the form of photons. This is related to the atomic structure of hydrogen, as the energy levels are determined by the arrangement of electrons. Studying these emissions is significant in understanding the behavior of atoms and has practical applications in fields such as quantum mechanics and astrophysics. These emissions can be observed in everyday life, such as in neon signs and stars, and their energy can be calculated using the formula E = hf.

[SOLVED] Photon emissions from hydrogen

Homework Statement


How many different photon emissions can hydrogen atom make going down from excited state 5 to ground level ?



Homework Equations



Thats what I'm lookin for.

The Attempt at a Solution



Simply by counting I got 10 different photon emissions.
But is there some equation for doing this elegantly ?

Isn't excited state 5 energy level n=6? So shouldn't there be 5+4+3+2+1 photons possible since from n=6, the electron can make 5 transitions, and from n=5 it can make 4 transitions, etc?

thanks, I got it

For excited state n there is (1+n)*n/2 possible different photon emissions.

FAQ: Photon emissions from hydrogen

What are photon emissions from hydrogen?

Photon emissions from hydrogen refer to the release of light energy in the form of photons when an electron in a hydrogen atom transitions from a higher energy level to a lower energy level.

How are photon emissions from hydrogen related to the atomic structure of hydrogen?

The energy levels of an atom are determined by its atomic structure, specifically the arrangement of electrons around the nucleus. When an electron moves from a higher energy level to a lower one, it releases energy in the form of photons, resulting in photon emissions from hydrogen.

What is the significance of studying photon emissions from hydrogen?

Studying photon emissions from hydrogen allows scientists to better understand the behavior and properties of atoms and the energy levels within them. This information is crucial in fields such as quantum mechanics and astrophysics.

Can photon emissions from hydrogen be observed in everyday life?

Yes, photon emissions from hydrogen can be observed in everyday life in the form of the visible light emitted by neon signs and fluorescent lights. Hydrogen is also present in stars, and its photon emissions can be observed through telescopes.

How is the energy of a photon emission from hydrogen calculated?

The energy of a photon emission from hydrogen can be calculated using the formula E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the emitted light. The energy of a photon emission is directly proportional to the difference in energy levels between the electron's initial and final states.
