In the phenomenon of electric discharge through gases at low pressaure the coloured glow in the tube appears due to 1 excitation of electrons in atoms 2collison between the atoms of the gas 3collison between the charged particles emitted from the cathode and atoms of the gas 4collison between different electrons of the atoms of the gas i think ans should be 3 am i correct please tell me rates assured please dont guess
