That's the interference of sound waves from the forks.

那是音叉发出的声波的干涉的结果。

The returning light beams merge together at the beam splitter and create an interference pattern of light and dark regions where the light waves either cancel out or reinforce each other.

返回的两束光在分束器处汇合，产生由亮区和暗区组成的干涉图案，图案中，光波要么相互抵消要么相互增强。

Existing UWB radars typically use a random noise signal to avoid interference between waves of the same wavelength.

现有的超宽频雷达为避免干扰，典型的方法是使用一个不规则声波发生器来规避和它波长相同的声波。

youdao

Since we're talking about wave functions, since we're talking about the properties of waves, we don't only have constructive interference, we can also imagine a case where we would have destructive interference.

因为我们讨论的是波函数，因为我们讨论的是波的性质，我们不仅有相长干涉，我们也可以想象在,某种情况下会有相消干涉。
