| 1 | This is the amplitude. | |
| 2 | The energy just gets bigger if the amplitude get bigger. | |
| 3 | Sound waves are measured by their amplitude. | |
| 4 | We'll give it a... amplitude, something like 30, maybe 35 centimeters. | |
| 5 | Remember the one-dimensional spring that we had a period which was independent of the amplitude? |
