Thank you theun here's your shmoop dooz your brought to

00:05

you by wave sources a wave source khun b a

00:08

machine creating a wave russ though the wave sources usually

00:11

waking up too late to do our hair all right

00:14

a source omits two waves in the same direction but

00:17

one happens Toa have twice the amplitude and frequency of

00:21

the other Which of the following outcomes could arise Select

00:25

two answers right here the options Constructive destructive nana large

00:29

german Alright let's imagine this scenario Here we are just

00:34

a regular sized wave wobbling are way down an access

00:37

when suddenly from behind us Here comes this monster wave

00:40

and it's twice as big as we are and has

00:42

twice the frequency Well it'd probably feel like getting chased

00:46

down by an nfl linebacker But we're dealing with waves

00:49

here And waves or energy not matter Waves don't collide

00:53

Exactly But they do Interact so we can scratch out

00:56

See when waves interact they create interference Well there could

01:01

be constructive interference which happens when waves of the same

01:05

sign either both positive or both Negative Come together All

01:08

right When there's constructive interference the waves add to each

01:11

Other creating a wave with a larger amplitude But if

01:15

the waves have opposite amplitude cz one positive and one

01:18

negative then they create destructive interference They cancel each other

01:22

out partially or entirely and their combined amplitude is smaller

01:26

Well in either case after the waves combined they cancel

01:29

each other out but just keep on moving back to

01:32

their original amplitude One wave does not absorb the other

01:35

so answer D is out the correct answers then our

01:38

a and b when they meet the waves either exhibit

01:41

constructive or destructive interference Sadly for us bedhead is usually

01:47

a case of destructive interference that no amount of hair 00:01:49.939 --> [endTime] gel can never reconstruct
