Question
Glass window panes are some time broken by an explosion even taking place far away. Why?
Solution
When explosion takes place at a far away place, the disturbance reaching the glass panes sets the glass panes into vibration.
If the frequency of vibration is equal to the natural frequency of window pane, then resonant vibration takes place and hence window panes break.
