Transcript

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
Full Transcript
- 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
