Photons and dileptons have long been considered as excellent probes of quark-gluon plasma (QGP) expected to be formed in relativistic heavy ion collisions. However, while evaluating these type of signals, the immediate interests were to study quasiparticle scattering in dense matter. In contrast, little has been done to account for the radiative or bremsstrahlung contributions to photons and dileptons from these quasi-particles. As will be shown these contributions are dominant as long as the energy remains below 1 GeV. It has also been argued that the system formed in relativistic heavy ion collisions undergoes rapid transverse expansion during the latter stages of the collision. Since low energy photons/dileptons are produced mostly from the late stage, they will be affected by the collective transverse flow. Therefore, one can get idea about the flow by studying low energy photons and dileptons. We apply soft photon approximation (SPA) to evaluate soft photons and dileptons from quark matter as well as hadronic matter. The estimations of soft electromagnetic radiations that exist in the literature have certain discrepancies (see Ref.  for details) which we have tried to correct in our calculations.
