Which as we’ve just said is determined by its amplitude.

—有关。刚才说过了这由幅决定。

Because it's the amplitude that determines how loud a sound appears to be to humans.

因为幅决定着声音对类来说有多响。

And then the magnitude of the original dipole.

然后是原始偶极子幅。

The wave’s wavelength and frequency determines their hue, and their amplitude determines their intensity or brightness.

决定光线色调，幅决定了强度或亮度。

A few important aspects of this wave include the frequency and the amplitude.

该波几个重要方面包括频率和幅。

And as you can see, the amplitude is increasing.

正如您所看到，幅正在增加。

Thousands of amplitudes for every single second of audio!

每秒钟数千个幅！

When you have notes that are very close together, the result is amplitude modulation.

当您音符非常靠近时，结果就是幅调制。

The amplitude of a sound wave determines how loud it is.

声波幅决定了响度。

30% chance of rain say quantum mechanics uses a related concept called amplitudes.

下雨概率是30%，量子力使用一个类似概念叫做幅。

It is not like we can increase the amplitude.

这不像我们可以增加幅。

When we say amplitude, do you mean probability?

当我们说到幅时，你是指概率吗？

And in a resonant cavity, the highest amplitude could be found at a quarter wave.

在共腔中，最高幅可以在四分之一波长处找到。

That's where your amplitude, that's where your energy is the highest.

那就是你幅，那就是你能量最高地方。

The heart rate was the same, but the amplitude dropped.

心率没变 但幅下降了。

In other words, if you double the wave’s amplitude, you get four times the energy.

换句话说，如果你将波 幅加倍，你会得到四倍能量。

We’ve also said that the intensity of a wave is proportional to the wave’s amplitude, squared.

我们还说过， 波强度与波幅平方成正比。

And! The radius of the circle is the same as the ball’s amplitude on the spring.

和！ 圆半径与球在弹簧上幅相同。

So, the cosine of theta is equal to the (ball’s position) divided by its (amplitude).

因此， theta 余弦等于（球位置）除以（幅）。

When the amplitude is modulated or changed, we hear this as a change in volume.

当幅被调制或改变时，我们听到是音量变化。
