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