Title: emission spectrum of the hydrogen atom
Post by: ainoko_hikaru 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.
