dc.description.abstract	We analyze a time sequence simultaneous G-band and Ca IIH images taken with Hinode/SOT on 14 April 2007 during 17:00-18:00UT. In each sequence, we selected 20 bright points and derived their light curves. Power-spectrum analysis was performed to determine periodicities in these light curves, which are 2-5min for the Gband bright points and 3-4 min for the Ca IIH bright points, respectively. Comparison of the light curves indicates the presence of a phase difference, which suggests the occurrence of propagating waves that may be responsible for heating the chromosphere in Ca IIH bright points.	en
