Wave characteristics Video transcript Let's say I've got a rope. And what I'm going to do is, I'm going to take the left end of the rope, and I'm going to jerk it up, and then back down. And we're going to talk about what happens or what possibly gets formed.
So if I take it up over here, it's going to, obviously, take the string to the right of it up with it. And the string is going to look something like this. It's going to look something like that. Now I'm going to immediately jerk it back down. And as it passes, let's see what the rope will look like when the left-hand point is at its original position again.
So the left-hand point-- I've pulled it back down.
But in the last time period, this part of the rope had some type of an upward velocity. You could imagine that way. And even after that point, even though this left-hand point starts getting pulled down, this point right here still has some upward momentum.
So it's still going to keep moving up, maybe at a slower pace because it's starting to be tugged down by the rope on its left.
So it's going to look something like that. And it's going to bring the rope to its right with it. So the rope will look something like this.
The rope might look something like that. And then I'm going to take this guy-- this was just an intermediate position on the way to being pulled all the way down here.
So what's the rope going to look like now? This guy, he had some momentum that got him there. But then all of that velocity will essentially go to zero because he's being tugged by the rope to the left.
And now, he's going to switch directions. And he will have gotten here, at that point. The point on the line that was here-- on the purple period of time-- it had some upward momentum. So it's just going to keep going, on maybe a slower pace. It'll be there and it will bring the rest of the rope to the right of it with it.
So now my rope is going to look something like this.
And then finally, where I'm going to jerk the rope back to its original position-- so this left-hand point is going to be there. This guy, in the previous time period, was moving down rapidly. So he might get there ready to switch directions again.
This guy will start moving down. This guy, right here, he had some upward momentum. So he's going to be up in this position now. And he's going to be ready to switch directions. So finally, when I've done this whole cycle, when I've moved up, down and back there again, my rope might look exactly like this.
And I could let go of the rope. I could just leave this little left point right there. And this the lump is going to propagate along the rope.
Because in the next moment of time, what's it going to look like? This guy is going to be pulled up by this left-hand point. So he'll go back to his resting position. This guy's being pulled down right here by the part of the rope to the left of him, so he's going to be pulled down.
This guy's being pulled down. But this guy had some upward momentum in the time period before, so he will have moved up. And so, the very next time period, my rope is going to look something like this.The behaviour of water waves.
GCSE Keywords: wave speed, wavelength, frequency, direction, refraction, reflection, diffraction. Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.
Wave, propagation of disturbances from place to place in a regular and organized way. Most familiar are surface waves that travel on water, but sound, light, and the motion of subatomic particles all exhibit wavelike properties.
In the simplest waves, the disturbance oscillates periodically (see periodic motion) with a fixed frequency and wavelength.
