And then if we look at these troughs right here, or these antinodes, rather, those are going to be areas where we have total constructive interference.

然后，如果我们观察这里的这些谷，或者更准确地说， 这些反节， 它们将成为我们拥有完全建设性干扰的区域。

Today, you learned about standing waves, and how they're made up of nodes and antinodes.

今天，我们了解了驻，以及如何 由节移中心组成。

And the open end will be an antinode, because that’s where there’s a peak in the oscillations.

开放端将是一个， 为那是振荡达到峰值的地方。

But the areas where molecules oscillate the most (including those near any open ends of the pipe) form the peaks, and therefore the antinodes.

但是分子振荡最多的区域（包括管道任何开口端附近的区域）形成峰，此形成。

You will have these little nodes and antinodes, but they are made up of traveling waves interfering with each other, bouncing back and forth.

你会看到这些小小的节，它们是由行相互干涉、来回反弹形成的。

If you look at a string on a stringed instrument, you can actually see where the nodes and antinodes are.

如果我们看弦乐器的弦，我们可以 查看节位置移中心。

It’s the simplest possible standing wave you can have, with the fewest nodes and antinodes.

这是您可以拥有的最简单的驻， 具有最少的节。

Today, you learned about standing waves, and how they’re made up of nodes and antinodes.

今天，您了解了驻， 以及它们如何由节组成。

Overtones build on the fundamental, incrementally: each overtone adds a node and an antinode.

每个覆盖添加一个节一个移中心。

Instead of having a node at each end, it has an antinode at each end.

不是在每一端都有一个结，而是 每端的中心移。

A standing wave in a pipe with two open ends is kind of the opposite, of the wave with two fixed ends: Instead of having a node at each end, it has an antinode at each end.

具有两个开口端的管道中的驻与具有两个固定端的相反：它不是在每一端都有一个节，而是在每一端都有一个。

So the peaks are the antinodes, and the points that don't oscillate are nodes.

所以顶是位移中心， 不动的是节。

The points of a standing wave that don’t oscillate are called nodes, and the points at the maximum height of the peaks are antinodes.

驻不振荡的称为节，峰最大高度处的称为。

So the fundamental standing wave for a pipe with two open ends will have two antinodes, and one node in the middle of the wave.

此， 具有两个开口端的管道的基本驻将有两个，一个节位于的中间。

And the open end will be an antinode, because that's where there's a peak in the oscillations.

开口端将是一个位移中心，为 顶部在示器中。

The second-simplest standing wave you can have on a string with two fixed ends has 3 nodes -- one at each end, and one in the middle -- plus 2 antinodes in between the nodes.

具有两个固定端的弦上第二简单的驻有 3 个节——每端一个，中间一个——加上节之间的 2 个。

Now what about the frequency of the second harmonic -- the standing wave with 3 nodes and 2 antinodes?

那么二次谐的频率呢... 具有 3 个节两个移中心的驻？

It's the simplest possible standing wave you can have, with the fewest nodes and antinodes.

它是可以获得的最简单的驻 在他们身上，最低的结移中心。

So the peaks are the antinodes, and the points that don’t oscillate are nodes.

所以峰是， 不振荡的是节。

And in its most basic form, it would have just one antinode, in the middle.

在其最基本的形式中，它将具有 中间有一个位移中心。
