AB: We examine oscillations in isolated three bright points co-temporal and co-spatial in photosphere and chromosphere in G-band and Ca II K line. Wavelet analysis was used to study wave packets and identify traveling magnetohydrodynamic waves. In general, it is thought likely that the photosphere and chromosphere oscillates in response to forcing by p-modes and granular buffeting, but they are also influenced strongly by presence of magnetic fields. The observed oscillations reveals evidence for kink-mode waves, traveling up through the chromosphere and coupling with sausage-modes waves. This provides a means for energy depositing in the upper chromosphere.
