Im not exactly sure what how to solve this with the way my teacher asked this question.
"For hydrogen atom transitions calculate E, v, and wavelength:"
Ni= 1
li= 0
Mli= 0
Msi= -1/2
Nf= 2
Lf= 0
Mlf= 0
Msf= -1/2
E(kj)= ?
v(Hz)= ?
wavelength(m)= ?
I think Ni is initial N.
and Nf is final N so the electron is making the transition from N = 1 to N = 2 so this is an absorption but the formula I list is for emission. That won't change frequency or wavelength but it will change the sign of E.
delta E = R(1/1 - 1/4)
where R = Rydberg constant of 1.0973E7 m^-1.
Then E = h*frequency with h = Planck's constant.
speed light = frequency x wavelength
