       VISIT: 'MATH IN ACTION' SITE A little girl is swinging in a park. His father pushes the swing now and then.The Swing has one frequency of oscillation.The father's frequency of pushes should match that of the Swing.Than only the swing will oscillate well. Here, the phenomenon "resonance" comes into play. We will see one more example.     An opera Singer Sings in high pitch. At one point of time, a wine glass Kept on a table breaks into pieces. Here, the frequency of the Singer matches the natural frequency of the wine glass. Hence, the glass vibrates violently and breaks away. Again resonance.     In 2000, on the London millennium bridge, Some 2000 people walked on it. It caused heavy wobbling of the bridge . The Engineers shut down the bridge immediately and made Some structural modifications to dampen resonance.     So what exactly is resonance? Let us study the definition.  " phenomenon of increased amplitude that occurs when the frequency of a perio
