Thank you We sneak and here's your shmoop du jour

00:05

brought to you by sound waves If you're listening to

00:07

this right now that means we're sending waves of sound

00:10

into your brain Creepy right But well we promise we'll

00:14

only use our powers for good How fast Sound wave

00:17

travels Depends on which of the following and hear the

00:20

pendulum answers forthem medium through in here Well sounds pretty

00:25

cool when you think about it It's created by invisible

00:28

waves that vibrate incredibly fast usually hundreds or thousands of

00:32

times a second That vibration then travels into our ears

00:35

which is pretty impressive Seriously go look at your ear

00:38

hole in the mirror like see how tiny it is

00:40

and that's it that's all it takes for us to

00:42

hear the whole universe of sound sound waves travel through

00:45

a medium which is our case usually the air But

00:48

they can travel through any substance really as long as

00:51

there are particles to pass the waves along in a

00:53

vacuum like space Well since there was no matter out

00:56

there sound can't travel twenty movie you watch where a

00:59

ship goes screaming through space blasting blazers and go you

01:04

you well guess what lies lies lies and what determines

01:09

the speed of the sound waves of the medium they

01:11

travel through so sound travels faster through water than it

01:13

does through the air faster through wood than it does

01:17

through water and faster to our mothers than to anyone

01:20

else in the world though for some reason that only

01:22

seems to apply the things that get us in trouble

01:24

In any case the correct answer to this question is

01:25

b medium through which sound is traveling but just because

01:28

we think it's pretty cool that we're still sending sound

01:31

waves and your brain lets go ahead and disprove the

01:33

other options Well the force with which the sound was

01:36

created determines how intense it is but it doesn't affect

01:39

the speed so is incorrect and interference with different sound

01:43

waves can make sound louder quieter but not faster or

01:46

slower Soc doesn't sound right either and sound and light

01:50

waves or different things Light is an electromagnetic wave and

01:54

sound is a physical wave They don't really interact at

01:57

all which rules out d c these sound waves were

02:00

painless and helpful if only all sound waves work that 00:02:02.91 --> [endTime] way
