Despr\u00e9s del frac\u00e0s que supos\u00e0 el model de Rutherford al no poder explicar, sense violar les lleis electromagn\u00e8tiques, com un electr\u00f3 orbitava al voltant del nucli d\u2019un \u00e0tom sense col\u2219lapsar-se cap aquest;
Bohr propos\u00e0 el seu model at\u00f2mic, recolzat per tres postulats que, com a tals, no eren demostrables. Amb aquest model, malgrat que sols era aplicable a l\u2019\u00e0tom d\u2019hidrogen i no acabava d\u2019explicar alguns fets, es va
poder avan\u00e7ar molt en la comprensi\u00f3 de la naturalesa qu\u00e0ntica de la mat\u00e8ria.
Entre altres coses, permetia calcular les longituds d\u2019ona que correspondrien a cadascuna de les radiacions emeses per la desexcitaci\u00f3 dels electrons entre diferents orbitals d\u2019un \u00e0tom d\u2019hidrogen. Aix\u00ed doncs, a partir de les formulacions matem\u00e0tiques dels diferents postulats del model at\u00f2mic de Bohr (allunyades de c\u00e0lculs
abjectes i alienants), en aquest projecte es realitzar\u00e0 una estimaci\u00f3 te\u00f2rica de les longituds d\u2019ona corresponents a la s\u00e8rie de Balmer.
A m\u00e9s, aquest treball ens permetr\u00e0 comparar cadascuna d\u2019aquestes transicions amb les franges del seu espectre d\u2019emissi\u00f3, les quals aconseguirem observar excitant els electrons dels \u00e0toms d\u2019hidrogen continguts en un tub de Geissler, com a conseq\u00fc\u00e8ncia del corrent que hi circula i que ha estat augmentat per una bobina de Ruhmkorff. Tot aix\u00f2, emprant nom\u00e9s estris no exageradament sofisticats i conceptes impartits durant 1r de Batxillerat, fet que fa d\u2019aquest treball digne de menci\u00f3.<\/p>\n
