Thank you We sneak and here's your smoke too Sure

00:05

brought to you by nodes which on a standing wave

00:08

our points of complete stillness energy go through them That

00:11

causes no movement You know like us After two hours

00:15

of physics homework that's What happened A certain standing wave

00:19

model has nine nodes How many anti nodes are present

00:23

and here Potential answer Already Ten eleven Let's take a

00:28

quick refresher course on standing waves A standing wave is

00:31

created when a wave generated at one end of a

00:33

medium is reflected back at the other end of the

00:36

medium the two waves aligned to create constructive in destructive

00:39

interference creating anti nodes of maximum displacement and nodes Where

00:43

there is no displacement eyes refreshing is ice water On

00:47

a summer day the starting point of a standing wave

00:49

is considered a node and the reflection point is also

00:52

a note This means that there was always one more

00:55

node than there are anti nodes in a wave so

00:59

if we have a wave with nine nodes than it

01:00

has to have eight anti nodes which means our answer

01:03

is a and we love questions like this It just

01:06

involved counting We canoe counting you know sometimes that's about

01:10

all we can do All right guys take off your 00:01:11.999 --> [endTime] shoes get your toes ready
