Thank you We sneak And here's your shmoop dooz your

00:06

brought to you by mechanical waves And no we're not

00:09

talking about what robots do it A baseball cool But

00:13

which of the following correctly rewrites the statement Mechanical waves

00:17

transport whatever physical quantity they travel through with constant speed

00:24

And here the potential answers All right Mechanical waves or

00:29

disturbances in matter That matter khun b air like when

00:35

our mom yells at us for leaving the drawers open

00:38

it will matter can be water like when we cannonball

00:41

into a pool It can even be a solid like

00:44

that around in an earthquake but in all of these

00:48

cases the matter isn't transported It just goes up and

00:52

down it doesn't move forward It stays there like us

00:56

after eating too much spaghetti dinner the wave causes motion

01:00

but when the wave has passed the matter is still

01:03

in its original position Here's another way to think of

01:06

it if we take a jump rope and move it

01:08

up and down will create a wave but the jump

01:11

rope won't actually go anywhere The wave is energy moving

01:14

through the rope but it's not transporting it so the

01:17

correct answer here is be matter is disturbed but not

01:21

transported Answer is incorrect because waves don't constantly accelerate or

01:25

decelerate waves can maintain a velocity or the velocity can

01:29

change and answer c is wrong because waves don't transfer

01:32

physical or non physical quantities Energy move through a medium

01:36

is part of a wave but no quantities or transferred

01:39

and we've already discussed why the original statements wrong so

01:41

the that's out too well since waves don't transport any

01:44

matter this is another reason why spring zahra Good analogy

01:47

for the actions of a wave A spring moves back

01:50

and forth or up and down without changing its location

01:53

We know a lot more about waves now which is

01:55

great We're going to go ahead and wrap this up

01:58

now so we'll say goodbye That feels a little incomplete

02:00

though if only there was some kind of gesture is

02:02

something we could do with our hand to add to

02:04

the whole goodbye process Huh Huh No no we're stumped
