Possible outcomes of surveys for extragalactic sources to be carried out by the next generation of ground based and satellite borne telescopes in the far infrared and sub-mm wavelengths are discussed. The confusion limits for several wavebands are computed. Surveys at wavelengths greater than 100 microns (i.e., beyond the dust emission peak) would allow detection of dust radiation from distant and primeval galaxies. The evolution of the metal content of galaxies could thus be investigated. The role of Cosmic Background Explorer (COBE) data in providing important constraints is discussed.
