These are the standing lava waves and kind of ebbed and flowed.

这些是屹立的熔岩浪，有些退潮了，还在流。

When you pluck a guitar string, you create a vibration called a standing wave.

当你拨弦时，你造出了一个振动，叫驻波。

They're standing waves similar to what you'd find in a wave pool but they are found out in Mother Nature.

这种波浪是驻波（静止的波浪），类似于冲浪池中的驻波，但它们是在大自然中发现的。

They can also take advantage of the superposition principle to create standing waves.

他们还可以利用叠加原理来产生驻波。

So by using the ultrasound, creating a standing wave and this small tiny small bead.

所以通过使用超声波，创造一个驻波和这个微小的小珠子。

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

今天，您了解了驻波， 以及它们如何由波节和波腹组成。

That's a standing wave, and it can happen both in strings and in the air in pipes.

这是一个永久性的浪潮，它可能会发生 在弦乐中，在声门的空气中。

And that's what makes music: Standing waves with different frequencies correspond to different musical notes.

海浪回应 站在不同频率的音乐音调。

But string, wind, and brass instruments use a special kind of wave — they're 'standing waves.'

但是弦，铜管乐器是用的 一种特殊的波… … 它们是“驻波”。

They look a little unnatural, but I think in future videos we'll show you how they're analogous to standing waves.

它们看起来有点不自然，但我认为在以后的视频中我们会向您展示它们与驻波的相似之处。

A standing wave is a wave that looks like it isn't moving.

驻波是波 它看起来像不动。

Now, in order to understand how standing waves operate, you should get to know their anatomy.

现在，这样我们就可以了解波浪是如何工作的 站着，你必须了解它的安装。

A string with two fixed ends -- like in a piano -- is probably the simplest way to understand standing waves.

双端和弦… … 就像钢琴… … 是 可能是理解驻波的最简单方法。

That’s a standing wave, and it can happen both in strings and in the air in pipes.

这是一个驻波， 它既可以发生在弦乐中， 也可以发生在管道中的空气中。

So we're gonna have a wave coming this way and a wave going this way, and it's gonna create standing waves.

所以我们会有一个波朝这边来，一个波朝这边走，它会产生驻波。

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波， 具有最少的波节和波腹。

This most basic kind of standing wave is known as the fundamental -- or the 1st harmonic.

这种主要类型的驻波被称为 基本上...... 或第一个兼容的曲调。

There are other, more complex standing waves that you can have, too.

还有其他更复杂的驻波 也可以获得。

So a standing wave's frequency will be equal to its velocity divided by its wavelength.

所以驻波的频率等于它的速度 波长划分。

This standing wave can have different numbers of nodes, allowing patterns to repeat themselves when there are more electrons around the nucleus.

这个驻波可以有不同数量的节点，当原子核周围有更多电子时，模式可以重复。
