Abstract: The waves observed in the chromosphere are interpreted as propagating acoustic waves in the interior of supergranulation cells, and as magneto-acoustic waves in the magnetic network on the cell boundary. The oscillation periods are the cutoff periods, respectively, of acoustic waves and of transverse magneto-acoustic waves. In addition to the oscillations of K_2v bright points and network bright points, which appear to be impulsively excited, there is a general oscillatory field in the quiet chromosphere, perhaps excited by short-period acoustic waves, generated by the turbulence of the convection zone. They may cause the chromospheric temperature rise that is observed in UV emission lines in the quiet cell interior everywhere and all the time.
