The discharge plasma was produced by anAC power supply source of 6 and 7 kHz frequencies for the nitrogen gasspectrum and for two different electrodes metals(Al and Cu). Optical emissionspectrometer was used to study plasma properties (such as electron temperature( ), electron number density ( ), Debye length ( ), and plasma frequency( )). In addition, images were analysed for the plasma emission intensity atatmospheric air pressure.
