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

—有关。刚才说过了这由它定。

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

因为定着声音对人类来说有多响。

And then the magnitude of the original dipole.

然后是原始偶极子。

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

定光线色调，定了强度或亮度。

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

该几个重要方面包括频率和。

And as you can see, the amplitude is increasing.

正如您所看到，正在增加。

Thousands of amplitudes for every single second of audio!

每秒钟数千个！

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

当您音符非常靠近时，结果就是调制。

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

声定了它响度。

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

下雨概率是30%，量子力学使用一个类似概念叫做。

It is not like we can increase the amplitude.

这不像我们可以增加。

When we say amplitude, do you mean probability?

当我们说到时，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，最高可以在四分之一长处找到。

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

那就是你，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 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， 强度与平方成正比。

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）除以它（）。

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

当被调制或改变时，我们听到是音量变化。
