Interference. |

If a peak of one wave meets a peak of another wave, what happens? |
The two waves and up. The particles where they meet would rise up towards the peak of the first wave and rise again towards the peak of the second wave, so they would end up twice as far from their centre point. |
Multiply. |

If you have two speakers playing the same note at the same volume, what happens? |
