Thank you here's Your shmoop du jour brought to you

00:05

by tuning forks although our favorite piece of musical silverware

00:09

is still the harmonizing butter knife When all right a

00:14

tuning fork is struck Which of the following describes the

00:17

sound wave produced and hear the potential answers a lot

00:20

of transfers lodge tunel Okay well sound waves could be

00:24

used for good like when our favorite song comes up

00:27

in our playlist or they could be used for evil

00:30

like when our neighbor decides to motel on at seven

00:32

in the morning anyway sound waves start when something vibrates

00:36

Those vibrations moving back and forth create longitudinal waves compressing

00:41

and expanding the air compression and expansion That means we're

00:46

dealing with longitudinal waves so answers a and b are

00:49

out and unlike trans verse waves longitudinal waves don't displace

00:53

matter The waves make particles within matter scrunch together or

00:58

get farther away But it's not like ripples in a

01:00

pond moving up in nam longitudinal waves carry energy and

01:04

momentum but they don't create displacement So the right answer

01:07

well that'll be option c and this makes sense if

01:10

we just consider how an object creates sound we think

01:13

of something vibrating we can see how it would compress

01:16

the air around it way just shouldn't try to actually

01:18

eat with a tuning fork will just end up hearing 00:01:21.939 --> [endTime] longitudinal waves coming from our empty stomach
