We model H-alpha and H-beta spectral lines in the presence of prominence oscillations. Since MHD waves cause oscillatory fluctuations of the plasma parameters (velocity, temperature, pressure, density), which are different at different depths, the resulting line profiles consist of particular contributions from a range of optical depths. We analyze temporal behavior of the line profiles, namely the Doppler shift, maximum intensity, and FWHM. Our simulations were performed for the fundamental and first harmonic slow and fast modes. The synthetic spectra can be compared with the observed ones collected during the joint Polish-Czech observational campaign devoted to a simultaneous detection of prominence oscillations from two distant sites.
