How to pronounce “slink” in English

But if the two slinkys have the same mass per unit length, the wave passes straight through.

And we can represent these parts with slinkys.

But since in this setup both slinkys are tied together, they're under the same tension.

It's like having two Slinkies that are quite different.

I've backed a desktop slinky treadmill, which does exactly that forever and ever.

He's been using an old slinky to slice his bananas.

There's just like a slinky apparatus to make the skirt go up and down and swirl around.

And then the next morning he'd kind of slink into the office and be like, oh Julia, I got that assignment I wanted.

Let's recreate Smith's signal by shaking a slinky up and down.

That's because how the wave actually travels through the slinky depends on two properties: how tightly the slinky is stretched, and this mass per unit length.

It's kind of like mass per unit length with the Slinkies.

It’s sort of like what happens when you pull a Slinky out on a flat surface from both ends, and push on one side.

So he gets her to back off as he slinks to his tree body.

I'd gone to 13 schools and I'd been able to slink out of doing regular physical activity due to a lot of excuses.

Now, so far we've used just one slinky, with one set of properties, to show how waves travel.

First, we're gonna try two very different slinkys.

from wherever he was from, "slinks across the floor of this House and adheres to his seat by his own slime."

And there's two ways you could make a wave with the slinky.

trying to raise money instead he just makes a jerk of himself and slinks out as the Rotary Club boots him off the

But when I increase the frequency to the point where the wave becomes shorter than the slinky itself, well, now when the wave reaches the fixed end,

So you might think Smith could do the same thing, except instead of matching slinkys, he had to match his transmission line to his antenna.

Some of it reflects, just like what we saw with the slinkys.

Do that, and it's like we've made the two Slinkies identical, no reflections.

all work together. And you can picture them if you imagine kind of holding a slinky in your hands.

See, if we start out with a long wavelength, the signal barely changes during the time it takes to travel down the slinky.

Since both the antenna and the transmission line have their own electrical properties, we can model Smith's whole system by tying two slinkys together.

Well, when we send a pulse down the line, it reaches the boundary between the two Slinkies.

If we can match this property, it's like the discontinuity is gone and it's just one slinky again.

Well, the mass per unit length decides how easy it is for a wave to travel through our slinky.

They move through rock more slowly, and they shear the particles side to side, or up and down, sort of like if I jiggle the Slinky like this.

Literally, one of the first ideas we had was, it seems like it should be able to flow like a Slinky.
