00:01
All right, so at t equals one second, the two waves will have moved one meter, since they're both moving at one meter per second.
00:10
So the top wave will now be going from one to five.
00:14
The bottom wave will be going from five to nine.
00:17
And so it'll look a little something like this.
00:19
They're the same size and shape as they were in the first case.
00:23
They're just one meter closer to each other each.
00:28
So two meters closer.
00:29
They've bridged the gap.
00:31
Now, at t equals two seconds, they start to interfere with each other.
00:36
And so the peaks will not have changed yet, since that part of the wave hasn't interacted yet.
00:45
But they're overlapping here in the middle...
