Harmonics of a Standing Wave - IB Physics

I explain the definition of harmonics in standing waves and show their shapes and patterns for strings that have 2 fixed ends, 1 fixed & 1 open end, and 2 open ends. I show how to find wavelength, velocity, frequency, and the fundamental frequency.
0:00 The velocity in a medium is constant
1:16 What is a harmonic?
3:06 2 fixed ends: reflection
5:02 2 fixed ends: wavelength of harmonics
6:49 2 fixed ends: frequency of harmonics
9:40 Example problem: 2 fixed ends
11:30 Fixed at 1 end: reflection
13:45 Fixed at 1 end: wavelength, frequency, & harmonic #
17:20 2 open ends: reflection
17:59 2 open ends: wavelength, frequency, & harmonic #

BEST EXPLANATION EVER!

I have discovered your channel a few days ago and realized there are such good videos. Thank you so much for the explanations and hope more people find your channel!

[@SKY-lf5sy]

hi! this video was very helpful and your explanation is really clear! thank you for continuing to upload :)

[@AdrianTangMusic]

thank you for making these 🙂

[@perfectneglect5770]

Oh my God you sounded so much like Chris Doner at 10:44 when you said 'Multiply that out'
Great video though, really helped me consolidate the ideas

[@HernandezLopezPedro]

thank you very much, your video was so helpful!

[@iCosmicRex]

man you are awesome

[@pavithranthayalan9378]

You're explaining very well, i would like to be a student in your class

[@sumeetrathore7946]

Thank you for explanation

[@alickmandala6744]

Good explanation

[@DJTejasMusic28]

this is amazing. Please please please do HL videos as well

[@AndyMasley]

Working on it! Been a busy school year so far but hoping to have time to make more soon

Does every harmonic need to end at an antinode? If not how comes the first harmonic at 18:30 doesn't stop at the antinode?

[@kevinpham928]

10:01 has equations

[@aditij3263]

at 16:25 shouldn't the wavelength be equal to 2/3L?

[@naveensingh5787]

what is the meaning of fundamental frequency

[@taanishqverma5253]

6:24 it should be 3/2 right?

[@annasek7123]

No, it should not. It is good. You can wright L=3/2 wavelength

[@taanishqverma5253]

6:39 the relation should be n/2 L
