And then you have another spherical wave coming from the short bank.

然后你会看到另一个来自短波岸的球面波。

So, as a spherical wave moves farther from its source, its intensity will decrease by the square of the distance from it.

因此，随着球面波远离其源，其强度将按距其距离的平方而减小。

So you can start seeing the waves are coming from the long bank here, and you can see they're making a spherical wave.

所以你可以开始看到波浪从这里的长河岸传来，你可以看到它们正在形成球面波。
