Here we have the sinusoid waves, which give us a sense of the frequency and wavelength of the electromagnetic wave.

里我们有正弦波，它们让我们了解电磁波的频率和波长。

That tends to be a little bit busier, so usually we just draw the sine wave.

那通常会复杂一点，所以我们通常只画出正弦波。

Well, if you multiply this signal by a sine wave of an arbitrary frequency, the two waves are uncorrelated.

好吧， 如果将此信号乘以任意频率的正弦波，则两个波不相关的。

These pressure variations can be modeled by a sine wave, where the peaks represent increased pressure and the troughs represent decreased pressure.
