In this problem we're giving a snapshot or a measurement of a weight passing a position of x equals 2 meters.
00:10
And it looks as follows.
00:16
And this with respect to time t in seconds, of course.
00:23
And y here is in centimeters.
00:29
And we see at minus one seconds, we're up at around 1 centimeter, i think.
00:39
And then we go at t equals 0 seconds at 2 meters.
00:46
We are at over here.
00:52
Then we continue to 1 .0, 2, 3.
01:01
And we reach 0 at 3 seconds.
01:07
Now we're going to draw this as a snapshot at t equals 0 seconds.
01:14
So, and the question is how we can do this.
01:18
What we know is that this wave has been moving right with one meter per second time.
01:29
We write x in meters.
01:33
Y is again there.
01:36
So we know that we have one, we have zero, we have two, we have three, and so on.
01:44
So we've been looking here at x equals 2 meters.
01:53
So at t equals 0 because that's what we're asked to plot, we know that this value is over here.
02:04
So that is 1 centimeter.
02:08
So we're up here...
