Constructive interference amplifies sound to make the overall combination louder.

相长干涉时声波振幅增大，使得声音组合的音量变大。

This phenomenon is called constructive interference, and it amplifies the wave, producing a brighter color.

这个现象叫做相长（建设性）干涉，它会把波放大，产生更亮的颜色。

Now, if you played both sounds at the same time, you'd get a phenomenon called constructive interference.

如果你同时播放这两个声音，会发生相长干涉的现象。

Constructive interference creates a visible, colored reflection, while destructive allows light to go through the oil to the water.

相长干涉会产生可见的彩色反射，而相消干涉则允许光穿过油进入水中。

So, different colors undergo a constructive interference at different angles.

因此，不同的颜色 在不同的角度会受到相长干涉。

Now, constructive interference through a single slit works a little differently.

现在，通过单个 狭缝的相长干涉的工作方式略有不同。

That's called constructive interference -- the waves build on each other.

这称为相长干涉。 波相互叠加。

Remember, when a wave is in phase with another wave, their crests and troughs are amplified, meaning that the light is brighter, thanks to constructive interference.

请记住，当一个波与另一个波同相时，它们的波峰和波谷被放大，这意味着光更亮，这要归功于相长干涉。

When the waves are an exact number of wavelengths apart, the crests and troughs will line up – creating constructive interference and a bright line.

当波相隔一定数量的波长时，波峰和波谷将对齐——产生相长干涉和一条亮线。

The bright lines are the result of constructive interference, when light waves build on one another, while the dark spaces in between are the result of destructive interference.

当光波相互叠加时，亮线是相长干涉的结果，而中间的暗线是相消干涉的结果。
