## Homework Statement

I'm supposed to determine e/m using Zeeman effect.

B=0.45 T

Difference between two spectral lines is also known (0.649x10^10 Hz)

## Homework Equations

Normal or anomalous Zeeman effect? How you know it?

I'm guessing normal, so

[tex]\Delta E = m_{l} \frac{e \hbar}{2m_{e}}B[/tex]

[tex]\Delta E = h \Delta f[/tex]

so,

[tex]\frac{e}{m_{e}} = \frac{h \Delta f2m_{e}}{m_{l} \hbar B} [/tex]

## The Attempt at a Solution

Well the attempt at solution is the equations I just wrote, are they right so far?

But the problem is, how I get [itex]m_{l}[/itex]? I think it's [tex]2l+1[/tex], but how I get [itex]l[/itex] from the know data then?
