| − | {{w|Resonance}} is the | + | {{w|Resonance}} is the tendancy for an object to oscilate when energy is transferred to it at a specific set of frequencies (known as {{w|harmonics}} of the natural frequency of the object). A simple example of this is pushing a child on a swing: by pushing the child at the right moment, more and more energy is transferred to the system and the amplitude of the oscilation grows. |
| − | In this comic, | + | In this comic, Person 2 is jiggling his leg up and down at a harmonic of the natural frequency of Person 1's desk. This causes Person 1's desk to vibrate more and more until objects on it start to bounce around. Rather than have Person 2 stop, Person 1 wants him to slightly increase the frequency of the jiggling in order to spill the drink on Steve's desk (which is not pictured). |
