Question

the charge-to-mass ratio of an electron May also be measured with zeeman effect, which gives rise to energy splittings in the presence of a magnetic field B. prove.

Answer 1

The charge to mass ratio of an electron may also be measured Zeeman splitting of mercury (Hg) green line. By studying the splitting of circularly polarized lines which are resulted from the transition:

`7 ^(3)S_(1) ---\ \textgreater \ 6 ^(3)P_(2)`

With the help of Fabry- Perot interferometer, The value of e/m is found to be (1.783) which is in agreement withthe measuredd values.
