在这种情况是相长干涉还是相消干涉？

In this case is it constructive or destructive interference?

youdao

这里是相消干涉。

We have destructive interference here.

youdao

如果我们减去干涉项，我们得到的就是相消干涉。

So if we're subtracting the interference term, what we have here now is destructive interference.

youdao

Just like we see destructive interference with water waves or with light waves, we can also see destructive interference with orbitals.

就像我们看到水波,和光波的相消干涉，我们也可以看到轨道的相消干涉。

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。

So we want to have constructive interference to form a bond, where as if we had destructive interference, we would not be forming a bond.

我们需要,相干相长来成键，如果，相干相消了，就不能成键，所以这时候。
