Recently the Solar Neutrino Observatory (SNO) group in Sudbury Canda, showed the first experimental evidence that neutrino produced in the Sun's core, change their flavour when they propagate. The most probably explanation of such phenomenon are the neutrino oscillation. In this work we give a pedagogical introduction to neutrino oscillation, both in the vacum and in the material medium, emphathizing the resonant MSW effect in the medium. This work is formulated for two neutrino generations however, we give a brief summary of three neutrino generations.
