Phenomenon of resonance
At resonance, rapid transfer of energy takes place resulting louder sound (booming sound). If two bodies having same natural frequency is placed side by side and if one of them is made to vibrate the other will automatically begin to vibrate. This effect is called resonance.Arrange two hollow sound boxes opened at one end such that their open ends face each other. Mount two tuning forks A and B of the same frequency on them as shown in the figure.
If one of the forks A is set into vibration, the other fork B also begins to vibrate and a loud sound is heard due to resonance.
