emission spectrum of the hydrogen atom
« on: August 01, 2008, 11:34:50 AM »
hello. i've been asked by my professor to solve a problem. i know how to attack it by using rydberg's constant, but she insists that we use B instead of RH. she didn't say what B is. I tried searching it but found nothing. help, please. it's not balmer though, i think. our topic is about bohr's theory of the hydrogen atom. the equation i'm talking about is emission spectrum of the hydrogen atom.

the equation is:

    En = -RH * (1/n2)

Could it be the einstein coefficient?  I have no idea about any of this, just random guessing...

uhm... maybe... i forgot to mention that the problem involves photons. the formula i used (the actual one) was

delta E = hv = RH * [(1/ni2) - (1/nf2)]

what she showed is

delta E = hv = B * [(1/ni2) - (1/nf2)]

not that this might change my question though.

thanks for the guess, macman104...

Rh is kinda fun to derive for yourself, this might be what she is trying to convey.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
